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

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\Prefetcher

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.

How to:


(Copy and Paste in notepad content between lines)


-----------------------------------------------------

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management\PrefetchParameters]
"EnableSuperfetch"=dword:00000001
"EnablePrefetcher"=dword:00000003

------------------------------------------------------


save and rename to .reg file extension, then import to reg. update reg and you should be good to go.
