Huh, they sure make a big change to performance :eek:

XP-64 all latest updates and .net 2.0
A64 4200+ @ 2.7ghz (11x245)
4x512 @ 2-3-3-12-12-2T 224.6mhz

Previous best run: 38.2xx
New best run: 34.996

All I did for tweaks was:


HKLM\System\CurrentControlSet\Control\Session Management\Memory Management\

"DisablePagingExecutive"=dword:00000001
"LargeSystemCache"=dword:00000001
-----------------------------
Disable last accessed timestamp:
Type into run: FSUTIL behavior set disablelastaccess 1

Probably not particularly fast given other things I also have running but i've not noticed that disable last accessed timestamp tweak around before so I did it as well as those other two pretty standard ones.

the way windows handles the ram and page file for the first two.

third is putting a timestamp on files after you edit/create them.

No, only kernel mode code and drivers wont be swapped, that is an old and known tweak :)


Here are another 2 NTFS tweaks:
fsutil behavior set mftzone 4
fsutil behavior set disable8dot3 1

timestamp writes info to all files you create, access, or modify that says when they were created, accessed, or modified. Right click any file and go to properties to see the info.

Dont need this for super-pi.. so away it goes :D

Oooh. Thanks for those.....i remember that setting largesystemcache in XP always meant failure to start!
