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. ----- Original Message ----- From: Jim Kenzig http://thethin.net <jimkenz@xxxxxxxxxxxxxx> Date: Thu, 30 Sep 2004 07:06:52 -0700 (PDT) Subject: [THIN] Re: Hyperthreading To: thin@xxxxxxxxxxxxx See http://www.2cpu.com/articles/42_1.html http://thethin.net/faqs2.cfm?id=444&category=1&sortby=score Leave it off for Win2K! http://thethin.net/faqs2.cfm?id=443&category=1&sortby=score Regards, Jim Kenzig http://thin.net Bob <bobmails@xxxxxxxxx> wrote: 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.
