Hyperthreading hurts 5.3?

[Timothy J. Luoma]

summary: should I disable hypertheading in the  BIOS when running 5.3?

Background info:

I have a new Dell Dimension 3000 running 5.3.

I noticed some huge pauses when copying a large # of files across the 
network.  Googling around found some information about earlier versions of 
5.x and Hyperthreading being detrimenatl for performance. 

Whether or not it was the source of the network copy problem, I am trying 
to decide if I should disable Hyperthreading.

Iif YES, I wasn't clear if people meant "disable in BIOS" or just some 
configuration setting in a *.conf file.

(disabling HT will apparently mean I have to reinstall XP on the other 
drive.  Not necessarily a bad thing, as it is supposedly also the way to 
solve the problem of my modem causing a BSOD in XP)

thanks
