I work on a lot of PCs at work and during my copious freetime for friends and families. I have come across a few tweaks that I have noticed that make a pretty good difference without investing much other than a few minutes of your time. Try them out and let me know what you think.
These Settings will fine tune your systems memory management –at least 256MB of ram recommended
go to start\run\regedit -and then to the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
DisablePagingExecutive -double click it and in the decimal put a 1 – this allows XP to keep data in memory now instead of paging sections of ram to hard drive yields faster performance.
LargeSystemCache- double click it and change the decimal to 1 -this allows XP Kernal to Run in memory improves system performance a lot.
Create a new dword and name it IOPageLockLimit – double click it and set the value in hex – 4000 if you have 128MB of ram or set it to 10000 if you have 256MB set it to 40000 if you have more than 512MB of ram -this tweak will speed up your disc cache
Reboot and watch your system fly!
