WARNING: Editing your registry is DANGEROUS and may render your computer UNUSABLE. Back up your registry before attempting any changes.
And now, onward...
Open Regedit.
Start >> Run >> regedit >> OK
Navigate to the key:
- Code: Select all
HKEY LOCAL MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
Double click DisablePagingExecutive and change the decimal value to 1.
This disables the paging function for the kernel and drivers, and loads them into RAM. (RAM is MUCH faster than your harddrive)
Double click LargeSystemCache and change the decimal value to 1.
This pulls the pins on XP's floodgate, and tells it to go all out.
Double click the IOPageLimitLock attribute. This may or may not be there, and if it isn't, you're done. Some versions of XP no longer have this key. Follow this chart of your computer's RAM when changing this key:
- Code: Select all
128 MB RAM: 4000
256 MB RAM: 10000
Anything beyond that: 40000
This specifies the number of bytes that Windows can use for I/O operations (input/output) and will provide an amazing boost in performance.
Enjoy!
