See whitepaper http://www.tmurgent.com/WhitePapers/WP_HyperThreading.pdf
If you don't have a problem, then great.

You don't want to use Hyperthreading on 2000 - there are some issues on that
OS. XP/2003 or above.
As to the mem/IO switch - I have to believe that memory is the best setting.
I don't know what the bios setting actually does, but presumably it is doing
something like playing with device priorities at the bus level.

I guess I have not noticed enough of an issue with hyperthreading, to turn
it off.

Hello there,
I found the settings on our BL20Ps last year when i was testing
Hyperthreading on Windows 2000.
I was checking the performance of a 16 bit application and then another
server with our core apps on.
I was most disappointed when i noticed zero difference when comparing with
other identical servers (save the bios change).
We had around 30 users for testing per box

See that's what I was thinking. all the I/O from the sessions. Mouse and
keyboard in particular.

Hmmm I/O is always the slowest so set it for best I/O. Of course I know
nothing on the subject but it is my best thought.

Ok, I just came across this in the BIOS settings when I went to turn off
hyperthreading. You can set the performance for the CPU to 'optimized for
memory' or 'optimized for I/O'. It is defaulted to 'optimized for memory'.
Anyone have any thoughts on this?
