Link to P4 Hyperthreading patch for XP

HT = dual processor technology. Winblows' HAL sees it as 'two'
processors. One virtual, other real. However, disabling HT in CMOS will
allow Winblows to see it as a single processor re HAL. I've noticed a
considerable performance loss, by doing that.

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."
