Windows XP tweaks:

The cache optimization

The cache optimization of Tweak-XP offers an increasement of system performance depending on the amount of physical memory installed in your PC.

If you have some extra RAM, you can speed up the file system activity by increasing the 'IoPageLockLimit' to 4096 Kbytes or more, depending on your amount of physical RAM. Choose from the options offered by Tweak-XP and save your changes. Remember that you'll have to restart Windows to activate the new settings.

  • 4096 KB (for machines with 32 MB or less RAM)

  • 8192 KB (for machines with 32+ MB RAM)

  • 16384 KB (for machines with 64+ MB RAM)

  • 32768 KB (for machines with 128+ MB RAM)

  • 65536 KB (for machines with 256+ MB RAM)

Harddisc optimizations:

This box offers several features to optimize Harddisc performance on Windows XP:

  • Clear pagefile (swapfile) on shutdown: This option forces Windows XP to clear the swapfile (virtual memory on your harddisc) on shutdown.
    Attention: with this feature enabled, the shutdown process of Windows XP might be much slower since the operating system needs some time to delete the swapfile.
  • Disable Windows File Protection: With Windows 2000 a new feature called Windows File Protection (WFP) was introduced, part of the System File Checker, which is intended to avoid some of the common DLL consistency issues. This feature may also block valid attempts to change system files and it can therefore be disabled by using this function of Tweak-XP.
    Note: This setting affects file scanning only. It does not affect the standard background file change detection that Windows File Protection provides.
  • Disable 8.3 Name Creation (NTFS): This feature of Tweak-XP stops the NTFS volume from generating MS-DOS compatible 8.3 file names. This can increase the performance on heavily used NTFS partitions that have large amount of files with long filenames.
  • Increase NTFS Performance by Disabling the Last Access Time Stamp: When Windows XP accesses a directory on an NTFS volume, it updates the LastAccess time stamp on each directory it detects. Therefore, if there are a large number of directories, this can affect performance.
  • Enable boot defrag for faster booting: Boot Defrag places all boot files next to each other on the disk for faster booting.

Core System Performance:

On systems with large amount of RAM (512 MB or more) this tweak can be enabled to force the core Windows XP system to be kept in memory and not be paged to disk.

Optimize CPU and Memory usage:

Using these two features you can force Windows XP to optimize the CPU usage for aaplications or background tasks. The memory usage optimization is available for applications and system caching.
