If you have a PC with reasonable amount of Memoery installed (lets say 512MB or a 1Gb) then this little registry tweak can help extract a little bit of an extra performance.

Windows Kernel loads and runs from the memory and hence allows faster application execution. However, there can be a time when the kernel components can be paged onto the Virtual Memory (Pagefile.sys) on the hard disk. This can directly impact the performace.

The following resitry tweak will help you restrict Kernel to run from the memory and not paged out to the Virtual memory.

1. Click Start – Run, type “regedit”

2. Navigate to

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]

\Session Manager
\Memory Management

3. In the right-pane, look for “DisablePagingExecutive” and set its value to “1″

4. Close the Registry Editor and restart your PC.

This should restrict Windows Kernel to the memory alone and will not be paged to the Virtual Memory on the Hard Disk.
