xeon/hyperthread with TS

[Alex Mondale]

I am looking for any URLs/materials where the technical specs for SMP
servers running terminal services clients are listed.

My boss at work claims that only *one* cpu is *ever* used by TS (w2k
advanced), and I'd like to prove him wrong.

We are also seeing ridiculously poor performance (our 2-cpu Xeon with
hyperthreading -- this means task manager and the like think it is a 4-way
box, so is it possible that TS also thinks it's a 4-way?-- with 2.5 gb RAM *
barely* manages 22 concurrent connections of TS clients ... this seems to be
5x too little!!!)

Any help at all is appreciated.
Thanks
Alex

Hi Alex,

When Hyper-Threading is enabled, the BIOS uses a logical to physical CPU
ratio. Current implementations are using 2:1 ratios meaning there are 2
logical CPUs for each physical CPU. I think TS also thinks it's a 4-way CPU
if you use 2 Xeon cpu. For licensing and supported configuration details,
visit the following Microsoft Web site:
