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.

1. run "regedit";
2. goto [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters\EnablePrefetcher];
3. Set the value to either 0-Disable, 1-App launch prefetch, 2-Boot Prefetch, 3-Both ("3" is recommended).
4. reboot.

It will decrease the boot time but double and increase the performance of your XP


High On Life!
thats weird!

Thats weird! mine was already set to 5! maybe because i have tweak xp? or becasue i ran bootvis(file from microsoft that helps boot your system faster) i put it to 3 so which is better 3 or 5?:confused:


5 is a "no value" that means prefetching is disabled. There has been a tweak suggestion around on the net recommending this wrong setting. Maybe some tweak programs still use it.
