what happens bad if i delete all the items in prefetch
folder? xp seems to start faster. can i disable prefetch?
thanks, jack
 
Prefetch can be disabled from a Registry Key.
"EnablePrefetcher" default value of 3, change to 0.
But Prefetch actually enhances XP's performance so
disabling it would actually result in slower boot and app
start times.

Click to expand...

Prefetch records, when a program loads, what files it reads in the
course of the load, and in what order. Then two things follow:

Next time the program is loaded, the system can arrange to get the
reads going immediately, instead of waiting to be asked - this speeds up
loading

It can arrange a mini-defrag in an otherwise idle time every few days,
which brings the files together in an optimal arrangement to speed
loading (including booting the system) yet more.

The overhead on the initial load of a program is small, the saving later
is bigger. The folder of data on my system is only about 5MB. So leave
it be
