[THIN] Re: OT?: HyperThreading

This article specifies "desktops".  Did you find anything specific to
"server"?
Microsoft* Windows* Operating System Desktop Based PCs

I know the article references Windows 2000 (All Versions) but seems to be
indicating P4 based desktop machines.

I would be interested to see if there are any known issues with the Xeon
processor based server models and Citrix Metaframe (Windows 2000 Server).

Ron,

My bad - sorry.  http://www.intel.com/support/platform/ht/os.htm

So far my testing indicates that lightly loaded servers perform better with
it turned off, heavily loaded servers with it turned on.  The OS gets fooled
into loading up logical processors on the same physical processor sometimes.
When I'm done I'll be getting this written up with the details.

If you have a handy link to the HP docs, please send.  I'll search for it if
you don't.
