Just read some interesting tweaks @ TweakXP and thought I'll pass them on to you. Thanks to Dr. Dong for the tweaks. The first "works" quite well so far. The second gave me a BSOD but perhaps it works for you: 1. Improve Your CPU's Performance 2. Increase Speed By Tweaking Prefetcher Settings Learn more about those two... German Translation @ Planet-XP.de :)

Improve Your CPU's Performance: Secondlevel Datacache [L2Cache] is very important for the performance of the CPU. Normally WinXP should recognize your CPU and the value of the L2Cache. However, sometimes XP can't do this or fails to do so. Therefore you can tweak it by yourself to improve the performance: Run "regedit" Goto [HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> ControlSessionManager -> MemoryManagement -> SecondLevelDataCache] Modify its value by decimalism: AMD Athlon XP - 256
Reboot Seems to work to some extent... Increase Speed By Tweaking Prefetcher Settings: This is an unique technique for XP, which could improve the performance significantly by tweaking the prefetcher. Recommended hardware: PIII 800 or higher, 512M RAM or more. Run "regedit" Goto [HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> ControlSession Manager ->Memory Management -> PrefetchParameters -> EnablePrefetcher] Increase the value ("5" is recommended) Reboot It will decrease the boot time but double and increase the performance of your XP. This one gave me a BSOD.
