Taken in context, that sentence applies to Windows Server 2003.

From that white paper?

 

"It is in this real-world environment

that leads us to weigh more heavily the results the results of "User Task"
testing

than that of the "CPU Intensive" applications. Thus we would recommend to

customers that they enable Hyper-Threading on their servers, assuming
licensing

and upgrade issues do not exist. On

average, we expect customers to

experience an average of 15% (ranging at

times from equal performance to 30%)

improved performance in real-world

situations when Hyper-Threading is

enabled on their processors."

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

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?
