go to start runregedit -and then to the following key

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory Management

1.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 harddrive yeilds faster performance.

2.LargeSystemCache- double click it and change the decimal to 1 -this allows XP Kernal to Run in memory improves system performance alot

3.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 disckcache

Reboot and watch your system fly.

    Be carefull with the LargeSystemCache switch. If you run a server it is very usefull however if, like myself, you have a gaming machine with lots of memory and use AGP Apature cache this can decrease performance greatly, as Microsoft mentions here:

    “When you enable System cache mode on a computer that uses Unified Memory Architecture-based video hardware or AGP, you may experience a severe and random decrease in performance. The Drivers for these components consume a large part of the remaining application memory when they are initialized during startup.”

    Otherwise the rest of the suggestions here are great!
