hey guys!
dunno if it's okay to post this here, but seeing as how you've mentioned the prefetch and process idle tasks tweaks, i'd really like to know if that works. I have done it myself, [just once so far], but have since came across articles that [kinda convincingly] say cleaning out the prefetch actually impairs performance as opposed to improving it.

article:
http://www.edbott.co...ves/000743.html

check out Ryan Myers[a developer on Microsoft’s Windows Client Performance Team]' blog too:
http://blogs.msdn.co.../25/421882.aspx

as for the the ProcessIdleTask API:
http://www.microsoft.../benchmark.mspx

in a nutshell: between these articles, they say that the cleaning out the prefetch folder temporarily hinders your system, and XP recreates the files anyway. also, the folder retains only 128 .pf files[doesn't take up too much space, nor cause too much of a diff].

as for calling the processIdleTask from the command line[or even batch files :) ], it actually keeps your system busy for at least 10 minutes after doing that...


that said, i'm kinda stumped and would appreciate it if you guys could talk about it. :tazz:

As far as Prefetch...it will repopulate on the next boot everytime you empty it...this adds to the startup time.
