Memory Performance Tweaks

There are several memory settings can be done with Windows XP - they are all located in
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Memory Management

part of the register.

Disable Paging Executive

With normal use. XP pages sections from RAM to disk, we can stop this and to keep the data in RAM, resulting in better performance. Note that only users with large amounts of RAM (256 +) should use this setting. The setting we want to go to disable the 'Paging Executive', as it is called, called DisablePagingExecutive. Change the value of this key 0-1 memory paging will be disabled.

System Cache Boost

Change the value of the key 0-1 LargeSystemCache tell Windows XP to allocate all but 4MB of memory for file system cache, basically means that the kernel of XP can run the memory, which improves its speed. 4 MB of memory available for disk caching, but if for some reason, needs to be done, XP allocates more. In general, this tweak improves performance a bit, 'but may in some intensive applications, degrade performance. As above tweak, you should have at least 256 megabytes of RAM before taking LargeSystemCache groped.

Input / Output Performance

This tweak is really valuable to anyone running a server - it improves performace while a computer is running large file transfer operations. The default is not displayed in the registry, so you'll need to create a REG_DWORD value called IoPageLockLimit. The data for this value is in bytes and defaults to 512KB on machines that have value. Most people using this tweak have found maximum performance from 8 to 16 megabyte range, so you have to play with the value of the search for the best performance. Remember that the value is measured in bytes, so if you want, say, 12MB allocated, it is 12 * 1024 * 1024 or 12582912 e As with all the memory settings, you should use this option if you have 256 MB of RAM or more.
