Yeah, don't bother.

Still nothing. I stand by my assumption that this is useless for systems with a decent amount of RAM on XP.

I saw this on HardForums about an hour ago and tried it out. I haven't really seen any improvement on my 2GHz Dothan w/ 1gB RAM, XP Pro SP2. Perhaps it would be more noticable on an older system with less RAM. Just a note, though, that Longhorn Blog above is from November of 2003 so future incarnations of those dev versions might have it included.
