From Tim Mangan's whitepaper on hyperthreading under 2003:
"The results in this paper are exclusively related to Windows Server 2003. We are currently running the tests used in the development of this paper under erver
2000. We can verify reports of performance and stability problems with Hyper-Threading on Windows 2000 Server, and at this time recommend customers disable Hyper-Threading under 2000."

So disable under 2000 is the recomendation, As to 2003 he shows a small performance increase in all cases except multithreaded CPU-bound applications, which is expected. Personally I leave hyperthreading turned on for my 2003 installs. It also makes single->dual cpu upgrades easier since the SMP kernal is already used =)
Thanks,

What are people's views on whether to enable or disable hyper-threading on a Proliant box running Windows 2003 as a DC. I remember Intel advised HT to be disabled on Windows 2000 but has this changed for Windows 2003?. Are the performance benefits significant for a DC?
Thanks
David
