<p>Windows 7 will run slower for a large amount of reasons, with all things from the software of your Pc not operating properly to your theory having some sort of error with its database settings. Despite being highly advanced, and one of the most popular versions of Windows ever released, it&#8217;s continually causing a large amount of problems that will lead the theory to slow down. To fix this issue, it&#8217;s highly recommended that you are first able to get rid of any issues that the software of your theory may have, as well as then ensure that Windows 7 has all the definite settings that it requires to run.</p>
<p>The way to speed up any Windows Pc, especially Windows 7, is to fix the problems that are manufacture it run slower. Although many computer heal technicians like to sell you extra hardware, the fact is that in 99% of &#8220;slow Pc&#8221; cases, the theory will be running slower thanks to the settings or software that control inside your Pc. This means that if you want to heighten the speed of your computer, no matter how &#8220;old&#8221; your hardware is, you need to be able to use a agenda or tool that&#8217;s going to heal the most problems that your Pc may have.</p>

<p>How To Speed Up Windows 7</p>
<p>The first step to speed up Windows 7 is to first ensure that your Pc has all its software working in the smoothest way possible. This should be done by uninstalling any programs that you don&#8217;t use any more. Most population don&#8217;t know this, but the more software you have installed on your computer, the less resources your Pc will have to process the settings that your other programs will need to run. This causes most Windows systems to run slower, and needs to be fixed first. To do this, click onto &#8220;Start&#8221;, then plump &#8220;Control Panel&#8221;. After that, locate &#8220;Uninstall A Program&#8221; and then click on any of the programs you don&#8217;t use / want any more &#8211; removing them wholly from your system.</p>
<p>The second step is to then clean out any registry errors that your computer may have. The registry is a central database which all Windows Pcs use to store their settings, options &#38; files. The registry is like the &#8220;Yellow Pages&#8221; for your theory &#8211; which is where it loads up the likes of your desktop icons, most modern emails and even your passwords. Although the registry plays a very prominent role for the flat execution of your system, it&#8217;s continually causing a large amount of problems &#8211; manufacture it vital that you&#8217;re able to use a registry cleaner tool to fix any of the potential problems that may be inside. This can fortunately done very well by downloading a &#8220;registry cleaner&#8221; agenda to fix all the potential errors that this database could have. This is well one of the more productive ways to speed up Windows 7, and can be done by using a tool such as Frontline Registry Cleaner 2.0.</p>

<content:encoded><![CDATA[<p><strong><span style="text-decoration:underline;">What&#8217;s this thing about?</span></strong></p>
<p>This post has a few main points:</p>
<p>1. Speeding up a filesystem&#8217;s performance by setting it up on a tuned RAID0/5 array.</p>
<p>2. Picking the fastest filesystem.</p>
<p>3. The fastest format options for Ext3/4 or XFS filesystems.</p>
<p>4. Tuning an Ext3/4 filesystem&#8217;s journal and directory index for speed.</p>
<p>5. Filesystem mount options that increase performance, such as <em>noatime</em> and <em>barrier=0</em>.</p>
<p>6. Setting up LILO to boot from a RAID1 <em>/boot</em> partition.</p>
<p>The title is a bit of an oversimplification <img src='http://s1.wp.com/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' />  The article is intended to keep being work in progress as &#8220;we&#8221; learn, and as new faster tools become available. This article is not intended to cover the fastest hardware (yet). The goal is the &#8220;fastest&#8221; filesystem possible on whatever device you have. Basically, &#8220;we&#8221; want to setup and tweak whatever is possible to get our IO writes and reads to happen quicker. Which IO reads? random or sequential? long or short? The primary goal is a quick Linux <span style="text-decoration:underline;">root</span> filesystem, which is slightly different than, lets say, a database-only filesystem, or a /home partition for user files. Oh, and by the way, do not use this on your production machines, people. Seriously.</p>
<p><strong><span style="text-decoration:underline;">RAID</span></strong></p>
<p><span style="text-decoration:underline;">WTF is RAID?!</span></p>
<p>The first question is, how many devices would you like your filesystem to span? The simple and correct answer is &#8211; the more the faster. To use one filesystem across multiple devices, a single &#8220;virtual&#8221; device can be created from multiple partitions with RAID. (Recently developed filesystems, like BTRFS and ZFS, are capable of splitting themselves intelligently across partitions to optimize performance on their own, without RAID) Linux uses a software RAID tool which comes free with every major distribution &#8211; mdadm. Read about mdadm <a title="Mdadm - Wikipedia" href="http://en.wikipedia.org/wiki/Mdadm" target="_blank">here</a>, and read about using it <a title="RAID Setup - Wiki" href="https://raid.wiki.kernel.org/index.php/RAID_setup" target="_blank">here</a>. There&#8217;s also a quick 10 step guide I wrote <a title="RAID HowTo" href="http://erikugel.wordpress.com/2010/04/11/setting-up-linux-with-raid-faster-slackware-with-mdadm-and-xfs/" target="_blank">here</a> which will give you an idea about the general procedure of setting up a RAID mdadm array.</p>
<p>Plan your array, and then think about it for a while before you execute &#8211; you can&#8217;t change the array&#8217;s geometry (which is the performance sensitive part) after it&#8217;s created, and it&#8217;s a real pain to migrate a filesystem between arrays. Not to mention a Linux root filesystems.</p>
<p><span style="text-decoration:underline;">Deciding on a performance oriented type of RAID ( RAID0 vs. RAID5 )<br />
</span></p>
<p>The rule of thumb is to use 3 or more drives in a RAID5 array to gain redundancy at the cost of a slight performance loss over a RAID0 array (10% CPU load at peak times on my 2.8 GHz AthlonX2 with a 3 disk RAID5 array). If you only have 2 drives, you cannot use RAID5. Whatever your situation is, RAID0 will always be the fastest, but less responsible, choice.</p>
<p>RAID0 provides no redundancy and will fail irrecoverably when one of the drives in the array fails. Some would say you should avoid putting your root filesystem on an un-redundant array, but we&#8217;ll do it anyways! RAID0 is, well, the *fastest* (I threw that caution to the wind and I&#8217;m typing this from a RAID0 root partition, for what it&#8217;s worth). If you are going to be or have been using a RAID0 array, please comment about your experiences. Oh, and do backup often. At least weekly. To an *external* drive. If you only have one drive you can skip to the filesystem tuning part. If you do are going to use RAID0/5, remember to leave room for a RAID1 array, or a regular partition, for <em>/boot</em>. Today, LILO cannot yet boot a RAID0/5 array.</p>
<p><strong></strong><span style="text-decoration:underline;">Deciding on a RAID stripe size</span><span style="text-decoration:underline;"> ( 4 / 8 / 16 / 32 / 64 / 128 / 256 &#8230; )<br />
</span></p>
<p>You will need to decide, for both RAID0 and RAID5, about the size of the stripe you will use. See how such decisions affect performance <a title="RAID Performance - Linux RAID Wiki" href="https://raid.wiki.kernel.org/index.php/Performance" target="_blank">here</a>. I find the best results for my personal desktop to be 32kb chunks. 64 does not feel much different. I would not recommend going below 32 or above 128 for a general desktops root partition. I surf, play games, stream UPnP, run virtual machines, and use a small MySQL database. If I would be doing video editing, for example, a significantly bigger stripe size would be faster. Such specific usage filesystem should be setup for their own need and not on the root filesystem, if possible. Comments?</p>
<p><span style="text-decoration:underline;">RAID 5 &#8211; deciding on a parity algorithm ( Symmetric vs. Asymmetric )</span></p>
<p>For RAID5, the parity algorithm can be set to 4 different types. Symmetric-Left, Symmetric-Right, Asymmetric-Left, and Asymmetric-Right. They are explained <a title="RAID 5 parity - Stack Overflow" href="http://stackoverflow.com/questions/5326325/raid-5-parity-placement-policy">here</a>, but they appear to only affect performance to a small degree for desktop usage, as <a title="spinics.net - Parity Algorithm" href="http://www.spinics.net/lists/raid/msg32428.html">one thread</a> summarized.</p>
<p><span style="text-decoration:underline;">Creating a RAID0 array</span></p>
<p>Using the suggestions above, the command to create a 2-disk RAID0 array for a root partition on <em>/dev/md0</em> using the partitions <em>/dev/sda1</em> and <em>/dev/sdb1</em> should look like this:</p>
<pre># mdadm --create /dev/md0 --metadata=0.90 --level=0 --chunk=32 --raid-devices=2 /dev/sd[ab]1</pre>
<p>Note the &#8211;metadata option, which with 0.90 specifies the older mdadm metadata format. If you will use anything other than 0.90, you will find Lilo failing to boot.</p>
<p><span style="text-decoration:underline;"><strong>The Fastest Filesystem &#8211; Setup and Tuning</strong></span></p>
<p><span style="text-decoration:underline;">Deciding on a Filesystem ( Ext3 vs. Ext4 vs. XFS vs. BTRFS )</span><strong><span style="text-decoration:underline;"><br />
</span></strong></p>
<p>The <a title="ilsistemista.net - Linux Filesystems Benchmarked" href="http://www.ilsistemista.net/index.php/linux-a-unix/6-linux-filesystems-benchmarked-ext3-vs-ext4-vs-xfs-vs-btrfs.html" target="_blank">Ext4 filesystem does seem to outperform Ext3, XFS and BTRFS</a>, and it can be optimized for striping on RAID arrays. I recommend Ext4 until BTRFS catches up in performance, becomes compatible with LILO/GRUB, and gets an FSCK tool.</p>
<p><span style="text-decoration:underline;">Deciding on a Filesystem Block Size ( 1 vs. 2 vs. 4 )</span></p>
<p>It is impossible to stress how important this part is. Luckily, if you don&#8217;t know what this is and just don&#8217;t touch it, most mkfs tools default to the fastest choice &#8211; 4kb. Why you would not want to use 1 or 2 is neatly shown in the <a title="Performance - Linux RAID Wiki" href="https://raid.wiki.kernel.org/index.php/Performance#RAID-5">benchmarking results of RAID performance on those block sizes</a>. Even if you are not using RAID, you will find 4kb blocks to perform faster. Much like the RAID geometry, this is permanent and cannot be changed.</p>
<p><span style="text-decoration:underline;">Creating an optimized for RAID Ext4 ( stride and stripe-width )</span></p>
<p>Use those guidelines to calculate these values:</p>
<pre>stride = filesystem block-size / RAID chunk.
stripe-width = stride * number of drives in RAID array ( - for RAID0, and that minus one for RAID5 )</pre>
<p>pass the stride and the stripe-width to mkfs.ext4, along with the block size in bytes, like this:</p>
<pre># mkfs.ext4 -b 4096 -E stride=8,stripe-width=16 /dev/md0</pre>
<p>A handy tool to calculate those things for you can be found <a title="MKFS Stride - uClibc.org" href="http://uclibc.org/~aldot/mkfs_stride.html" target="_blank">here</a>.</p>
<p><span style="text-decoration:underline;">Creating an optimized XFS filesystem ( sunit and swidth )</span></p>
<p>The XFS options for RAID optimization are sunit and swidth. A good explanation about those two options can be found in <a title="Optimizing Performance - MythTV Wiki" href="http://www.mythtv.org/wiki/Optimizing_Performance" target="_blank">this post</a>. A quick and dirty formula to calculate those parameters was taken from <a title="RAID and XFS" href="http://webcache.googleusercontent.com/search?q=cache:nbUxpV-UO54J:feedblog.org/2008/06/18/howto-configure-raid-strides-in-xfs/+raid+with+xfs&#38;cd=12&#38;hl=en&#38;ct=clnk&#38;client=iceweasel-a" target="_blank">here</a>:</p>
<pre>sunit = RAID chunk in bytes / 512
swidth = sunit * number of drives in RAID array ( - for RAID0, and that minus one for RAID5 )</pre>
<p>The sunit for a 32kb (or 32768 byte) array would be 32768 / 512 = 64</p>
<p>The command to create such a filesystem for a 32kb chunk size RAID0 array with 2 drives and a 4096 (4kb) block size will look something like this:</p>
<pre># mkfs.xfs -b size=4096 -d sunit=64,swidth=128 /dev/md0</pre>
<p><span style="text-decoration:underline;">Tuning the Ext3 / Ext4 Filesystem ( Journal )<br />
</span></p>
<p>There&#8217;s a good explanation about the 3 modes in which a filesystem&#8217;s journal can be used on the <a title="Speeding Up EXT3 - OpenSUSE Wiki" href="http://en.opensuse.org/SDB:Speeding_up_ext3" target="_blank">OpenSUSE Wiki</a>. That same guide will rightly recommend avoiding writing actual data to the journal to improve performance. On a newly created but unmounted filesystem, disable the writing of actual data to the journal:</p>
<pre># tune2fs -O has_journal -o journal_data_writeback /dev/md0</pre>
<p><span style="text-decoration:underline;">Turning on Ext3 / Ext4 Directory Indexing:</span></p>
<p>Your filesystem will perform faster if the directories are indexed:<span style="text-decoration:underline;"><br />
</span></p>
<pre># tune2fs -O dir_index /dev/md0
# e2fsck -D /dev/md0</pre>
<p><strong><span style="text-decoration:underline;">Filesystem Mounting Options ( noatime, nodiratime, barrier, data and errors</span><span style="text-decoration:underline;"> options ):</span></strong></p>
<p>Some options should be passed to the filesystem on mount to increase its performance:</p>
<p><em>noatime, nodiratime</em> &#8211; Do not log access of files and directories.</p>
<p><em>barrier=0</em> &#8211; Disable barrier sync (Only safe if you can assure uninterrupted power to the drives, such as a UPS battery)</p>
<p><em>errors=remount-ro</em> &#8211; When we have filesystem errors, we should remount our root filesystem readonly (and generally panic).</p>
<p><em>data=writeback</em> &#8211; For Ext3 / Ext4. If your journal is in <em>writeback</em> mode (as we previously advised), set this option.</p>
<p>My fstab looks like this:</p>
<pre>/dev/md0         /                ext4        noatime,nodiratime,data=writeback,stripe=16,barrier=0,errors=remount-ro      1   1</pre>
<p>And my manual mount command will look like this:</p>
<pre># mount /dev/md0 /mnt -o noatime,nodiratime,data=writeback,stripe=16,barrier=0,errors=remount-ro</pre>
<p>Did I mention to NEVER do this on a production machine?</p>
<p><span style="text-decoration:underline;">Installing your Linux</span></p>
<p>Install as usual, but do not format the <em>root </em>partition you&#8217;ve setup! If you are using RAID0/5, you have to setup a separate, RAID1 or primary <em>/boot</em> partition. In my experience, the leaving the boot partition unoptimized does not affect regular performance, but if you are keen on shaving a few milliseconds off your boot-time you can go ahead and tune that filesystem yourself as well.<span style="text-decoration:underline;"><br />
</span></p>
<p><span style="text-decoration:underline;">Making sure LILO boots</span></p>
<p>If you are using RAID0/5 for your <em>root</em> partition, you must setup a separate non-RAID or RAID1 partition as <em>/boot</em>. If you do setup your <em>/boot</em> partition to be on a RAID1 array, you have to make sure to point lilo to the right drive but editing <em>/etc/lilo.conf</em> :</p>
<pre>boot = /dev/md1</pre>
<p>and make sure LILO knows about the mirroring of the <em>/boot</em> partitions by adding the line:<em></em></p>
<pre>raid-extra-boot = mbr-only</pre>
<p>Then, LILO must be reinstalled to the Master Boot Record while the <em>/boot</em> partition is mounted on the <em>root </em>partition. From a system rescue CD, with a properly edited <em>lilo.conf</em> file this will look something like this:</p>
<pre># mount /dev/md0 /mnt
# mount /dev/md1 /mnt/boot
# /mnt/sbin/lilo -C /mnt/etc/lilo.conf</pre>
<p>&#8230; and reboot.</p>
<p><span style="text-decoration:underline;">Experience and thoughts:</span></p>
<p>I&#8217;ve been following my own advice for the last couple of weeks. The system is stable and best of all, *fast*. May those not be &#8220;famous last words&#8221;, but I&#8217;ll update this post as I go. The only thing we all really need is comments and input. If you use something else that works faster for you &#8211; let us know. If something downgraded your stability to the level of Win98, please let us know. More importantly &#8211; if you see any errors, you got it &#8211; let us know.</p>
<p><span style="text-decoration:underline;">TO DO:</span></p>

<description><![CDATA[Since defragging the disk won&#8217;t do much to improve Windows XP performance, here are 23 suggest]]></description>
<content:encoded><![CDATA[<p>Since defragging the disk won&#8217;t do much to improve Windows XP performance, here are 23 suggestions that will. Each can enhance the performance and reliability of your customers&#8217; PCs. Best of all, most of them will cost you nothing.</p>
<p>1.) To decrease a system&#8217;s boot time and increase system performance, use the money you save by not buying defragmentation software &#8212; the built-in Windows defragmenter works just fine &#8212; and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.</p>
<p>2.) If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.</p>
<p>3.) Ensure that Windows XP is utilizing the NTFS file system. If you&#8217;re not sure, here&#8217;s how to check: First, double-click the My Computer icon, right-click on the C: Drive, then select Properties. Next, examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key. This process may take a while; it&#8217;s important that the computer be uninterrupted and virus-free. The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.</p>
<p>4.) Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a &#8220;searchable keyword index.&#8221; As you can imagine, this process can be quite taxing on any system.</p>
<p>The idea is that the user can search for a word, phrase, or property inside a document, should they have hundreds or thousands of documents and not know the file name of the document they want. Windows XP&#8217;s built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for.</p>
<p>Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you&#8217;re a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disabling it.</p>
<p>Here&#8217;s how: First, double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck &#8220;Allow Indexing Service to index this disk for fast file searching.&#8221; Next, apply changes to &#8220;C: subfolders and files,&#8221; and click OK. If a warning or error message appears (such as &#8220;Access is denied&#8221;), click the Ignore All button.</p>
<p>5.) Update the PC&#8217;s video and motherboard chipset drivers. Also, update and configure the BIOS. For more information on how to configure your BIOS properly, see this article on my site.</p>
<p>6.) Empty the Windows Prefetch folder every three months or so. Windows XP can &#8220;prefetch&#8221; portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That&#8217;s fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.</p>
<p>7.) Once a month, run a disk cleanup. Here&#8217;s how: Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button &#8212; it&#8217;s just to the right of the Capacity pie graph &#8212; and delete all temporary files.</p>
<p>8.) In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to &#8220;DMA if available&#8221; for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.</p>
<p>9.) Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets. A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support &#8220;cable select,&#8221; the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.</p>
<p>10.) Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search &#38; Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.</p>
<p>11.) Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility. Here&#8217;s how: First, click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don&#8217;t want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.</p>
<p>12.) Remove any unnecessary or unused programs from the Add/Remove Programs section of the Control Panel.</p>
<p>13.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here&#8217;s how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer &#8212; only its responsiveness.</p>
<p>14.) If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.</p>
<p>15.) Visit Microsoft&#8217;s Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.</p>
<p>16.) Update the customer&#8217;s anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.</p>
<p>17.) Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts &#8212; that is, anything over 500 &#8212; will noticeably tax the system.</p>
<p>18.) Do not partition the hard drive. Windows XP&#8217;s NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called &#8220;D drive.&#8221; You&#8217;ll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won&#8217;t be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won&#8217;t need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.</p>
<p>19.) Check the system&#8217;s RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC&#8217;s memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.</p>
<p>20.) If the PC has a CD or DVD recorder, check the drive manufacturer&#8217;s Web site for updated firmware. In some cases you&#8217;ll be able to upgrade the recorder to a faster speed. Best of all, it&#8217;s free.</p>
<p>21.) Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.</p>
<p>22.) If you&#8217;re sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip: open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to &#8220;Launch folder windows in a separate process,&#8221; and enable this option. You&#8217;ll have to reboot your machine for this option to take effect.</p>
<p>23.) At least once a year, open the computer&#8217;s cases and blow out all the dust and debris. While you&#8217;re in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For more information on this leaking-capacitor phenomena, you can read numerous articles on my site.</p>
<p>Following any of these suggestions should result in noticeable improvements to the performance and reliability of your customers&#8217; computers. If you still want to defrag a disk, remember that the main benefit will be to make your data more retrievable in the event of a crashed drive.</p>

<description><![CDATA[In this times of computer technology, we all put our work with the use of computer.  this common too]]></description>
<content:encoded><![CDATA[<p>In this times of computer technology, we all put our work with the  use of computer.  this common tool helps us make our work easy, fast and  credible. It is mostly used in schools, offices, government agencies  and other establishments.</p>
<p>Computer play a vital role in our daily work so as a computer user  must learn how to take care this kind of tool and even upgrade its  performance.  One good thing that helps a computer come up with a good  processing performance is about activex.  Here are some information  about <em><strong><a href="http://www.speedypc.com/articles/virtual_memory_problems.aspx">virtual memory</a></strong></em>.</p>
<p>In computing terms, virtual memory represents a type of  memory addressing or management method which is commonly applied to  computer systems that perform multitasking operations<strong>.</strong> In  modern operating system platforms, multitasking gives the computer user  the ability to maximize his computing time by allowing different  processes in the background.</p>
<p>These processes consume a portion of the Random Access Memory (RAM) installed on the machine. The RAM acts as a temporary storage area for vital information required by the running processes<strong>.</strong> Since RAM storage is considerably faster compared than other types of  storage, it allows the computer system to run multiple applications  without a noticeable loss in performance.</p>
<p>Virtual memory includes the process of swapping between the  hard drive (and similar high capacity devices) and the RAM (active  storage)<strong>.</strong> The virtual memory makes use of the hard drive as a  type of memory address space (hence the term &#8220;virtual&#8221;) to supplement  RAM capacity. Unfortunately, this commonly leads to a slowdown because  the access speed of the hard drive is slower compared to the RAM.</p>
<p>The display of the &#8220;virtual memory is low&#8221; alert is one of the most  annoying and alarming messages that can be seen in any computer system.  Basically, this means that the amount of RAM installed in the machine is  not sufficient to cater to all running programs. One of the simplest  solutions to this problem is to upgrade your RAM capacity.</p>
<p>Another common problem associated with virtual memory is the  incorrect size allocation. Essentially there is no right or wrong amount  of virtual memory that can be specified for a machine. Since virtual  memory is considered mainly as a backup for when the RAM is used up, the  amount is largely dependent on how the computer system is configured  (hardware-wise) and used.</p>

<content:encoded><![CDATA[<p>Someone has obviously discovered my <a href="http://necoro.wordpress.com/2009/05/08/firefox-directory-in-ram/">old post about moving the .mozilla directory of firefox into RAM</a>. Unfortunately it did not work anymore and I also stopped using it (one reason: well &#8211; it did not work, second reason: my computer was quite unstable for some time and thus I lost quite often my FF-data).</p>
<p>But now I took the time to look into it and fix it. I also moved it from bzr to git: It can now be found at <a href="https://github.com/Necoro/moztmp">github</a>.</p>
<p>Feel free to play around with it. And if you want to add nice features: do so. Remember that it is quite easy to fork and push-back repositories with git and github :)</p>

<content:encoded><![CDATA[<p style="text-align:left;">
<p><a href="http://farekx.files.wordpress.com/2011/02/speed-up-windows-7-meter1.jpg"><img class="alignleft size-full wp-image-173" title="speed-up-windows-7-meter" src="http://farekx.files.wordpress.com/2011/02/speed-up-windows-7-meter1.jpg?w=208&#038;h=164" alt="" width="208" height="164" /></a>Perhatian khusus telah diberikan oleh tim Windows 7 untuk membuat nya lebih cepat daripada sistem operasi sebelumnya. Windows 7 jauh lebih cepat daripada Windows Vista, tetapi bahkan kemudian kebanyakan dari kita tidak bisa puas dengan yang  sudah kecepatan default yang terinstal pada PC/Laptop kta . Ada banyak orang yang masih memiliki PC lama, dan setelah menginstal  dan menjalankan Windows 7 terasa lamban, akhirnya mereka tetap memilih Windows XP agar nyaman dalam bekerja.</p>
<p>Pada postingan kali ini, saya  berbagi cara singkat untuk mengoptimalkan setingan pada Windows 7 agar anda dapat berkerja dengan nyaman atau setidaknya bisa  membuatnya  Windows 7 anda dengan cepat dan menikmati kinerja system anda maksimum. Saya jamin bahwa setelah mengikuti panduan <!--more-->ini dan melaksanakan rekomendasi pada PC, Anda benar-benar akan mendapatkan sistem Windows 7 yang performa.</p>
<p>Persyaratan Minimum PC :</p>
<p>1) 1GHz processor (32- or 64-bit)<br />
2) Memori 1GB<br />
3) Harddisk16GB<br />
4) Mendukung untuk DX9  graphics 128MB memory (untuk interface Aero)<br />
5) DVD – R/W drive</p>
<p>Bahkan jika Anda tidak memiliki kartu grafis DX 9 tidak ada masalah, karena targetnya adalah kinerja.</p>
<p><strong>Panduan</strong><strong> </strong><strong>Mempercepat</strong><strong> </strong><strong>Windows</strong><strong> </strong><strong>7</strong></p>
<p>v  <strong><em>Menonaktifkan Fitur Index pencaharian </em></strong></p>
<p><strong><em><a href="http://farekx.files.wordpress.com/2011/02/search111.jpg"><img class="size-full wp-image-176 alignnone" title="search1" src="http://farekx.files.wordpress.com/2011/02/search111.jpg?w=562&#038;h=377" alt="" width="562" height="377" /></a><br />
</em></strong></p>
<ul>
<li>Klik kanan icon &#8220;Computer&#8221; di desktop dan pilih &#8220;Manage&#8221;.</li>
<li>Klik &#8220;Services and Application&#8221; di jendela &#8220;Computer Management&#8221;.</li>
<li>Klik &#8220;Services&#8221;.</li>
<li>Anda dapat melihat banyak layanan terdaftar di sana. Cari &#8220;Windows Search&#8221;,</li>
<li>Klik kanan pada &#8220;Windows Search&#8221; dari daftar dan pilih &#8220;Properties&#8221;.<br />
jendela Windows Search Properties akan terbuka. Dari klik &#8220;Startup type&#8221; pada drop down menu dan pilih &#8220;Disabled&#8221;.</li>
<li>Klik &#8220;Apply&#8221; kemudian &#8220;OK&#8221; dan hanya itu. Fitur Pencarian Pengindeksan sekarang dinonaktifkan.</li>
</ul>
<p><strong> </strong></p>
<p>v  <strong><em>Nonaktifkan</em></strong><strong><em> </em></strong><strong><em>Tema</em></strong><strong><em> </em></strong><strong><em>Aero</em></strong></p>
<ul>
<li>Klik kanan pada Desktop dan pilih &#8220;Personalize&#8221; klik Window Color Tab.</li>
<li>Hilangkan centang pada Kotak &#8220;Enable Transparency&#8221; dan kemudian klik pada &#8220;Open classic appearance properties for more color options&#8221;.</li>
<li>Lalu jendela akan terbuka. pilihlah Standard theme atau basic theme. <strong> </strong></li>
</ul>
<p><a href="http://farekx.files.wordpress.com/2011/02/aero1.jpg"><img class="alignnone size-full wp-image-177" title="Aero" src="http://farekx.files.wordpress.com/2011/02/aero1.jpg?w=433&#038;h=356" alt="" width="433" height="356" /></a></p>
<p>Ini dimaksudkan agar memori grafis anda tidak terpakai banyak dalam tampilan latar, karena jika interface grafis diaktifkan maka memori kartu grafis anda dipakai secara maksimal. Jadi jika kita peduli pada kecepatan, nonaktifkan Aero pada windows akan mendapat kecepatan ekstra.</p>
<p>v  <strong><em>Menonaktifkan</em></strong><strong><em> Visual Effects tidak diinginkan</em></strong></p>
<ul>
<li>Klik kanan pada &#8220;Computer &#8221; dan pilih &#8220;Properties”.</li>
<li>Klik pada &#8220;Advanced System Settings&#8221; dari sebelah kiri untuk membuka jendela &#8220;System Properties&#8221;.</li>

<ul>
<li>Pilih &#8220;Custom:&#8221;. Sekarang hilangkan centang pada semua pilihan dan hanya memilih tiga opsi saja, yaitu Smooth edges, use drop shadows dan use visual styles. (lihat screen shot). Setelah itu klik Apply dilanjutkan dengan klik OK.  (untuk melihat hasil dari perubahan tersebut, Restart komputer).</li>
</ul>
<p style="text-align:center;"><a href="http://farekx.files.wordpress.com/2011/02/visual211.jpg"><img class="size-full wp-image-185 aligncenter" title="Visual2" src="http://farekx.files.wordpress.com/2011/02/visual211.jpg?w=248&#038;h=368" alt="" width="248" height="368" /></a></p>
<p>Ini dimaksudkan agar tidak menonaktifkan tampilan yang menggunakan animasi .</p>
<p>v  <strong><em>Menonaktifkan</em></strong><strong><em> Layanan yang tidak diinginkan untuk Mempercepat Windows 7</em></strong></p>
<p>Ada banyak layanan di windows 7 yang sebenarnya jarang sekali atau tidak diperlukan dalam penggunaan sehari-hari. Contohnya layanan seperti &#8220;print spooler&#8221; hanya dibutuhkan saat kita menggunakan printer. Jika penggunakan printer hanya kadang-kadang saja, maka layanan ini dapat dimatikan dan dihidupkan pada saat ingin menggunakan printer tersebut.</p>
<p><strong>PENTING:</strong> Untuk mengatur layanan (Services) dengan aman, maka sebaiknya di set ke MANUAL saja, jangan di set ke DISABLE. Hal ini karena ketika windows membutuhkan  layanan  tersebut,  secara otomatis dapat diaktifkan. Tapi jika di set ke Disable maka layanan tersebut tidak dapat diakses oleh windows dan anda harus melakukannya dengan manual.</p>
<p>Daftar Layanan (Services) yang harus di set ke manual. (langkah untuk melakukannya seperti pada <strong><em>Menonaktifkan Fitur Indeks Pencaharian </em></strong>di atas).</p>
<p>1. Application Experience</p>
<p>2. Computer Browser <em>(Jika PC tidak terhubung dengan jaringan/network)</em></p>
<p>3. Desktop Window Manager Session Manager <em>(Jika tidak menggunakan aero effects)</em></p>
<p>4. Diagnostic Policy Service</p>
<p>5. Distributed Link Tracking Client</p>
<p>6. IP Helper</p>
<p>7. Offline Files</p>
<p>8. Portable Device Enumerator Service</p>
<p>9. Print Spooler <em>(Jika anda tidak menggunakanPrinter)</em></p>
<p>10. Protected Storage</p>
<p>11. Remote Registry <em>(Anda dapat dengan aman menonaktifkannya  Keamanan/Security)</em></p>
<p>12. Secondary Logon</p>
<p>13. Security Center</p>
<p>14. Server <em>(Jika komputer Anda tidak terhubung dengan jaringan apapun)</em></p>
<p>15. Tablet PC Input Service</p>
<p>16. TCP/IP NetBIOS Helper</p>
<p>17. Themes <em>(Jika Anda menginginkan aero dan tampilan visual yang baik (classic theme akan diterapkan))</em></p>
<p>18. Windows Error Reporting Service</p>
<p>19. Windows Media Center Service Launcher</p>
<p>20. Windows Search <em>(Jika Anda jarang menggunakan fitur Pencarian windows)</em></p>
<p>21. Windows Time <em>(Jika Anda tidak ingin untuk melakukan sinkronisasi waktu sistem dengan waktu internet secara otomatis)</em></p>
<p>Menonaktifkan servis yang tidak diperlukan di Windows 7 benar-benar dapat mempercepat waktu boot sistem.</p>
<p><strong> </strong></p>
<p>v  <strong><em>Nonaktifkan fitur User Account Control (UAC) </em></strong><em> </em></p>
<p><a href="http://farekx.files.wordpress.com/2011/02/uac11.jpg"><img class="alignleft size-full wp-image-188" title="UAC" src="http://farekx.files.wordpress.com/2011/02/uac11.jpg?w=443&#038;h=327" alt="" width="443" height="327" /></a>* Dari Control Panel  buka &#8220;User Accounts and Family Safety&#8221;&#62; User Account.</p>
<p>* Klik link Change Account User Control Setting.</p>

<p>v  <strong><em>Nonaktifkan Fitur Thumbnail Preview untuk mempercepat  browsing  File</em></strong></p>
<p>Fitur ini oleh Windows 7 akan menampilkan thumbnail kecil isi folder bukannya menunjukkan  ikon. Karena itu banyak menguras sumber daya sistem. Jadi dengan menonaktifkan  fitur  Thumbnail Preview, dapat mempercepat browsing file pada  explorer.</p>
<p><a href="http://farekx.files.wordpress.com/2011/02/thumbnail-preview1.jpg"><img class="alignnone size-full wp-image-197" title="thumbnail preview" src="http://farekx.files.wordpress.com/2011/02/thumbnail-preview1.jpg?w=469&#038;h=501" alt="" width="469" height="501" /></a></p>

<li>Klik “Apply” dan dilanjutkan dengan “OK”.</li>
</ul>
<p>v  <strong>Nonaktifkan Screen Saver dan Wallpaper</strong></p>
<p>Dalam menampilkan  wallpaper  dan screen saver membutuhkan memori.  Jadi dengan menonaktifkan  keduanya, anda dapat menghemat beberapa Mega Bytes memori.</p>
<ul>
<li>Klik kanan pada desktop dan pilih &#8220;Personalize&#8221;.</li>
<li>Klik link Screen Saver, Dari drop down menu Screen Saver, set untuk&#8221;None&#8221;dan klik&#8221;Apply&#8221;dan kemudian&#8221;OK&#8221;.</li>

<description><![CDATA[My personal experience with SSDs began with an Intel X25M that I built into a Lenovo Thinkpad R61. I]]></description>
<content:encoded><![CDATA[<p>My personal experience with SSDs began with an Intel X25M that I built into a Lenovo Thinkpad R61. It replaced a Seagate 160 GB 5400rpm which in combination with Windows Vista &#8230; well, let&#8217;s just say, it wasn&#8217;t that fast.</p>
<p>The SSD changed everything. It was not just faster, it was downright awesome! As if I had a completely new computer.</p>
<p>With that in mind I thought about my desktop PC. It&#8217;s a little more than 2 year old Windows XP box, Intel Core2Duo 2.7 GHz, 4GB RAM, with a not so slow Samsung HDD. I use it mainly for programming, which is most of the time <a title="Grails.org" href="http://www.grails.org/" target="_blank">Grails</a> programming under IntelliJ IDEA.</p>
<p>And let me tell you, the Grails + IDEA combination can get dog slow at times. The start-up time of IDEA alone gives you time to skim over the first three pages of <a title="Hacker News" href="http://news.ycombinator.com/" target="_blank">Hacker News</a> and read the latest <a title="XKCD" href="http://xkcd.com/" target="_blank">XKCD</a>.</p>
<p>So the plan was to put an extra SSD into the Windows box and put only programming related stuff on it. This would save me the potential hassle of moving my whole system but would still give me development speed-up.</p>
<p>I had to be a little careful because the standard settings for IDEA&#8217;s so-called &#8220;system path&#8221; and &#8220;config path&#8221; is in the user&#8217;s home directory. (Btw, this settings can be changed in file &#8220;idea.properties&#8221; which resides in &#8220;IDEA_INSTALLATION_DIR\bin&#8221;, e.g.: c:\Progam Files\JetBrains\IntelliJ IDEA 9.0.4\bin)</p>
<p>I think you already guessed the result. Three words: fast, faster, SSD. It&#8217;s just amazing! IDEA start-up is so fast now, I barely have time for a quick look at the newest headlines on <a title="InfoQ" href="http://www.infoq.com" target="_blank">InfoQ</a>.</p>
<p>The next step is of course to put the whole system on SSD but that will probably have to wait until we upgrade the whole company to Win7. Can&#8217;t wait&#8230; <img src='http://s0.wp.com/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> </p>

<content:encoded><![CDATA[<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;">Last week I showed you some tips for speeding up your PC, I hope it worked for you, if they didn&#8217;t here are some more!</p>
<p><span style="font-family:Verdana, Tahoma, Arial, sans-serif;font-size:11px;color:#2a2a2a;"> </span></p>
<div class="entry">
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;"><a href="http://www.syzygy.org.uk/wp-content/uploads/2010/06/286892_ofcomm_series_-_collapsed.jpg" style="font-weight:bold;text-decoration:none;color:#c9740a;"><img class="alignright size-full wp-image-396" title="286892_ofcomm_series_-_collapsed" src="http://www.syzygy.org.uk/wp-content/uploads/2010/06/286892_ofcomm_series_-_collapsed.jpg" height="204" alt="" style="float:right;margin:3px;padding:2px;" width="300" /></a><strong>1. Check if you may have a virus slowing your PC</strong></p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;">A common reason for a PC running too slowly is that a virus has made its way on your hard drive and started duplicating itself like mad or using up valuable system resources and memory, severely slowing down your computer.&#60;!&#8211;more&#8211;&#62;</p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;">Scan for spyware or virus using your favorite virus scanner, or use AVG free antivirus software or a good online solution like MacAfee Freescan &#8211; see &#160;<a href="http://www.mcafee.com/freescan" style="font-weight:bold;text-decoration:none;color:#c9740a;">www.<strong>mcafee</strong>.com/free<strong>scan</strong></a></p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;"><strong>2. Disable unused network ports or other controllers</strong></p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;">Do you have any unused network connections that you could disable, or even any other PCI slot devices that you could remove totally if not in regular use?</p>
</div>
<p>&#160;</p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;"><span style="font-family:Verdana, Tahoma, Arial, sans-serif;line-height:16px;font-size:11px;color:#2a2a2a;"><strong>3. Run Scandisk&#160;</strong></span>Try running scandisk to check for system file errors or bad sectors that could be repaired.</p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;"><strong>Right click on C drive &#8211;&#62;</strong><strong>&#160;Click Properties &#8211;&#62;</strong><strong>&#160;Click Tools &#8211;&#62;</strong><strong>&#160;Click Check Now &#8211;&#62;&#160;</strong><strong>Check both boxes and click Start</strong></p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;">A scan will be scheduled for the next time you start your computer.&#160; Beware &#8211; it can take a long time so it might be a good idea to leave it running overnight rather than get annoyed when you need to start your computer in a hurry!&#160; Use a UPS if your power supply is unreliable.</p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;"><strong>4. Operating System needs updating</strong></p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;">Sometimes an operating system can have certain bugs or need patches and updates in order for it run correctly.&#160; It&#8217;s also important to get security updates to avoid getting viruses that slow down your computer. It&#8217;s best to manually update otherwise you can waste time getting a lot of unnecessary software which is what we try and avoid.&#160;<img class="wp-smiley" src="http://www.syzygy.org.uk/wp-includes/images/smilies/icon_smile.gif" alt=":)" style="margin:0;padding:0;" /></p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;"><strong>5. Do not show Hidden Files</strong></p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;">Sometimes showing hidden files is useful but it also means your GUI has to load up all these random hidden files, most of which are temporary ones and this can slow down your PC.</p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;">In any windows folder&#160;<strong>Click Tools &#8211;&#62;</strong><strong>&#160;Click Folder Options &#8211;&#62;</strong><strong>&#160;Click View &#8211;&#62;</strong><strong>&#160;Click Do not show hidden files and folders &#8211;&#62;</strong><strong>Click OK</strong></p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;"><strong>6. Check what processes and programs are running</strong></p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;">Hit&#160;<strong>Ctrl Alt Delete</strong>&#160;(all at the same time) to start the task manager, then click processes to see which application is using most of your system resources. &#160;Closing something using a lot of resources before running a software application can help speed it up.</p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;"><strong>Highlight the appropriate process &#8211;&#62;</strong><strong>&#160;Click End Process</strong></p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;">Beware of closing any old process: look up the name on Google first to find out what it is. You can also identify primitive viruses this way so keep an eye out for things that look strange. Lots of normal programs do have strangely named processes though.</p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;"><strong>7. Slow PC in games?</strong></p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;">You can also play around with video card settings to get the best smoothest game play while sacrificing some graphics quality.</p>
<p style="line-height:1.5em;text-align:justify;margin:0 0 15px;padding:0;"><strong>Right click your desktop &#8211;&#62;</strong><strong>&#160;Click Properties &#8211;&#62;</strong><strong>&#160;Click Settings &#8211;&#62;&#160;</strong><strong>Click Advanced &#8211;&#62;&#160;</strong><strong>Click on your graphics card control panel and follow on-screen instructions</strong></p>

<content:encoded><![CDATA[<p>In my first post about calculating covariance matrices quickly I explained how to apply the ideas presented in a paper<em> by Fatih Porikli, Oncel Tuzel</em>. I showed a basic 2nd year university method for calculating cells based on reusing previous calculations (where the answer was stored in another cell).</p>
<p>I mentioned that the code can further be sped up by removing the if&#8217;s. I&#8217;ve done that and want to show the results.</p>
<p><strong>Here is the old code;</strong></p>
<p><a href="http://rossrichardson.files.wordpress.com/2010/05/code-after2.png"><img class="alignnone size-full wp-image-13" title="P covariance code after" src="http://rossrichardson.files.wordpress.com/2010/05/code-after2.png?w=404&#038;h=351" alt="P covariance code after" width="404" height="351" /></a></p>
<p>But you&#8217;ll see that after <em>xd</em> and <em>yd</em> are above 1 the ifs become quite useless and waste time. A good way to further increase speed is just to <em>expand </em>the code, so I removed them.</p>
<p><strong>Here is the new code;</strong></p>
<p><a href="http://rossrichardson.files.wordpress.com/2010/05/codeenhanced.png"><img class="size-full wp-image-26 alignnone" title="code enhanced" src="http://rossrichardson.files.wordpress.com/2010/05/code-enhanced.png?w=587&#038;h=399" alt="code enhanced" width="587" height="399" /></a></p>
<p>You&#8217;ll see that for the very first cell we seed the value, and then calculate the top and left columns. From then on, no more if!</p>
<p>And finally the average timings in MATLAB on an i5-750, win7;</p>
<p><strong>Timings;</strong></p>
<p><span style="text-decoration:underline;">Before</span></p>
<p>P (Time ms.): 0.012948<br />
Q (Time ms.): 0.081901</p>
<p><span style="text-decoration:underline;">After</span></p>
<p>P (Time ms.): 0.0094849 (136% faster)<br />
Q (Time ms.): 0.073851 (111% faster)</p>

<content:encoded><![CDATA[<p><a href="http://schneide.files.wordpress.com/2009/09/fotolia_10291909_xs.jpg"><img class="alignleft size-medium wp-image-897" style="border:1px solid black;margin:5px;" title="© Friedberg - Fotolia.com" src="http://schneide.files.wordpress.com/2009/09/fotolia_10291909_xs.jpg?w=188&#038;h=148" alt="© Friedberg - Fotolia.com" width="188" height="148" /></a>In the <a href="http://schneide.wordpress.com/2009/09/15/speed-up-your-buildbox-part-i-introduction-harddisk/" target="_blank">first</a> <a href="http://schneide.wordpress.com/2009/10/19/speed-up-your-buildbox-part-ii-processor/" target="_blank">three</a> <a href="http://schneide.wordpress.com/2009/11/16/speed-up-your-buildbox-part-iii-memory/" target="_blank">parts</a> of our effort to speed up our buildbox, we replaced the harddisk with a RAM disk, upgraded the CPU to the top-notch model and installed plenty of fast RAM. This brought the build time down from 03:30 minutes to around 02:00 minutes. The CPU frequency was the biggest time saving factor in our case study. Two minutes is as fast as the build can get for our project without fiddling with the actual build process. It&#8217;s sufficient for our case, but it may not for yours.</p>
<p><strong>Even top speed is too slow</strong></p>
<p>Lets assume we maxed out the hardware and still have a build duration far beyond the magical ten minutes mark. What can we do now? There are two viable options at hand if you can exclude the possibility that your build process is really inefficient and needs optimization. In the latter case, it would be better to revise the process instead of the build infrastructure.</p>
<p><strong>Two ways to speed up your build infrastructure</strong></p>
<p>You can go down one or both of two general paths to speed up your build process. To understand the examples, lets assume the build takes 20 minutes to run on your top-notch build box.</p>
<ul>
<li><strong>Add more build boxes.</strong> This is the classical &#8220;parallelize it!&#8221; approach. It won&#8217;t speed up the individual build process, but enable more processes to run at the same time. This approach wont change anything if your team does seldom check-ins, which in itself is an anti-pattern to continuous integration. But if your team commits changes every ten minutes, having at least two build boxes will prevent the second committer from waiting 30 minutes on the CI results. Instead, the results will always be there after 20 minutes. You haven&#8217;t exactly sped up your build process, but the maximal waiting time of your committers. For details on the implementation, see below at &#8220;<em>Growing a build park</em>&#8220;.</li>
<li><strong>Chop up your build process.</strong> This is known as &#8220;staging&#8221; or <a href="http://www.infoq.com/news/2007/09/CI_Pipeline" target="_blank">&#8220;pipelining&#8221; your build</a>. This won&#8217;t speed up the individual build process, either, but deliver certain partial results of your build earlier. Lets assume you can split your build process into four distinct stages: compile, unit test, integration test, package. Whenever a stage yields a result, the comitter gets feedback immediately. In our example, this might be every 5 minutes. This has several disadvantages, as for example discussed in <a href="http://www.juliansimpson.org/2007/07/pipeline-of-doom.html" target="_blank">the article &#8220;The pipeline of doom&#8221; by Julian Simpson</a>, but can lower the waiting time for specific aspects of your build drastically. You haven&#8217;t exactly sped up your build process, but the response time for partial results and therefore the average waiting time of your committer. For details on the implementation, see below at &#8220;<em>Installing a build pipeline</em>&#8220;.</li>
</ul>
<p><strong>Growing a build park</strong></p>
<p>If you want to reduce the initial waiting delay of a build before it gets processed or increase the throughput of builds, the build farm pattern is your way to go. By adding slave build machines to your build master, you can distribute the workload on more shoulders. The best way to set up your infrastructure is to introduce a dedicated master box that only delegates actual builds to its slaves. The master box handles the archivation of build artifacts and deals with the web server requests, while the slaves only perform build tasks. The master box can be of average power, with increased storage size, while the slaves should be ultra-fast, without the need of big disks. Solid state disks or even RAM disks of the slaves can be tuned to actual workspace sizes, as it is all that needs to be stored there.</p>
<p><strong>Distributed builds with Hudson</strong></p>
<p><a href="http://wiki.hudson-ci.org/display/HUDSON/Distributed+builds" target="_blank">The Hudson continuous integration server has a strength in setting up these master/slave scenarios</a>. It&#8217;s ridiculously easy to set up a build slave. You basically only need to click on a link to start the slave process. If you happen to have a standard build, everything needed gets downloaded automatically. If you want your slaves to operate automatically, you can install a windows daemon, provide a SSH account or write your own script. Usually, slaves are set up in a matter of minutes without hassle. A great idea is to <a href="http://weblogs.java.net/blog/2009/06/07/starting-hudson-slave-live-usb-media" target="_blank">turn powerful collegue boxes into build slaves (aka CI zombies) by booting an USB stick</a>. The best way to start with master/slave builds is to turn your current PC into a hudson slave right now by using <a href="http://wiki.hudson-ci.org/display/HUDSON/Distributed+builds#Distributedbuilds-LaunchslaveagentviaJavaWebStart" target="_blank">the Java Web Start method</a>.</p>
<p><strong>Installing a build pipeline</strong></p>
<p>If you are interested in early but incomplete feedback from your build box, staging your build will help you out. If partitioned right, you&#8217;ll receive a series of answers on specific questions from your build process. The questions may be like:</p>
<ol>
<li>Will it compile?</li>
<li>Will it pass the unit tests?</li>
<li>Will it function (pass the integration tests)?</li>
<li><a href="http://www.blendtec.com/willitblend/" target="_blank">Will it blend?</a></li>
</ol>
<p>Ok, the last question is rather unlikely to be answered by your build box. The overall build process will not be any faster, but basic safety test results are reported earlier. If you combine this approach with distributed builds, there is the possibility to designate specifically tuned machines to different stages. The Hudson continuous integration server has the ability to tag a slave with different labels. You can then configure your build to only run on slaves with the desired label assigned.</p>
<p><strong>Staged builds with Hudson</strong></p>
<p><a href="http://wiki.hudson-ci.org/display/HUDSON/Splitting+a+big+job+into+smaller+jobs" target="_blank">Staging with the Hudson continuous integration server</a> isn&#8217;t as easy as the master/slave feature, but there are some plugins that allow for more complex setups. You might experience some functionality that&#8217;s still under development, but basic staging is possible even today. In combination with specialized slave build boxes, this approach can lower your build duration. It is a a complex endeavour, though.</p>
<p><strong>Conclusion</strong></p>
<p>Once your single build box is maxed out but still not fast enough, you enter a different realm of continuous integration infrastructure setups. Speeding up a build process beyond the single box isn&#8217;t as easy as installing more RAM. But with a fair amount of planning, you have a fair chance to improve the situation. Note that you won&#8217;t primarily lower build duration, but increase throughput and utilize partitioning and specialization. These are different measures and might not affect the wall clock time of your build. The combination of staging and distribution is the most powerful setup, but will result in the most complex infrastructure to maintain. Before entering this realm, be sure to apply any possible optimization to your build process. Because you&#8217;ll not leave that realm again soon.</p>
