Link to P4 Hyperthreading patch for XP
HT = dual processor technology. Winblows' HAL sees it as 'two'

I've noticed a considerable performance loss, by doing that. - Curtis Newton stood up, at show-n-tell, and said: On Sat, 12 Jul 2003 22:48:59 +0100, "Chris" wrote: Hi, sorry for the cross post but I have the update for Hyperthreading for XP home and pro. I have posted this on the bottom of my personal web site. http://www.ckccomp.plus.com/site/PAGE2.htm It will be in SP2 but for those that can't wait here it is. Perhaps I am reading it wrong, but knowledge base article 815227 is for a computer with more than one logical processor; not for a hyperthreading computer with only processor. "SYMPTOMS A program that uses large mapped file views to share information between two processes may experience a significant performance decrease. The performance degradation occurs in the UnmapViewOfFile function. CAUSE This problem occurs if you install Windows XP Service Pack 1 (SP1) on an Intel Pentium 4 computer that has more than one logical processor." - -- Strontium "Shortcuts are self-defeating. Mean.
