[THIN] Re: Hyperthreading

Hmm did you see the link for Microsoft about using HT on Windows Servers on 
that page?

Those links from Intel were for Desktop Processors though. There is a
seperate information page for Xeon HT's for servers.

Xeon Information: http://www.intel.com/design/Xeon/

Very interesting discussion though. Personally I have not disabled HT
on those Xeon Servers that we support.

Even on our latest VM Servers I have left it on as VMWare ESX 2.x now
can see "HT". Whether it actually utilizes HT is another question.

Has anybody experimented with Hyperthreading On -vs- Off on Win2k
servers? I've heard rumblings that it can be problematic, and perhaps
decrease performance. I noticed that most SpecInt. winners have it
disabled. I'm considering disabling it on one of my farm servers to
observe the results. If anybody else has experimented I'd love to
hear about it.

Thanks in advance,
Bob
