For a good Use of  Memory system of your PC Try this setting for U regedit:

enter in regedit ----> hkey local machine ----> System ----> controlset001 ----> control ----> Session Manager ---->  Memory management

Create a new DWords and Rename IOPageLockLimit ( write exactly word )

if you have 512 Mb of Ram modified this value in 80000 esadecimal ( 512x1024 )

if you have 1024 Mb of Ram write in esadecimal 100000 ( 1024x1024)

if you have 2048 mb of Ram write in esadecimal 200000 ( 2048x1024 )

Modified a Dword SecondLevelDataCache ( L2 Processor ) whit amount of L2 of your processor ( 512 - 1024 - 2048 ecc ecc  )

try also a tweak of Prefetch:


"microsoft wrote"

Microsoft claims Longhorn will be, er, faster

The only reason why its faster is they added a superfetch feature to the prefetcher. If you look at the key:

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementPrefetcher

you will notice in windows xp

EnablePrefetcher = 3 and you will notice in windows longhorn
EnableSuperfetch = 1

Well, guess what? You can put the EnableSuperfetch = 1 in windows xp and get the same speed.

Wow, Microsoft just added a feature that was already there in xp.
