high page faults/sec and high context switches/sec on CITRIX server SERVER 2003

We have performanc issues on our CITRIX servers witch run IFIX application.

The symptoms i have are:

It is a SERVER 2003 BARE METAL on a HS21 blade with CITRIX 4.5 installed.

1) very high context switches/sec (209287) on AVG
2) high page faults/sec: +-4000
3) high CPU +80% on AVG.
4) more than 30% CPU is in Privileged Mode CPU

=> I found what to measure but what is the cause? (is it a lack of memory, is it a bug in the application, ..)

Is the software SMP aware or is the affinity all bound to a single core?

Might be worthwhile enabling memory and CPU throttling.

Also might be worthwhile graphing it - one user at a time.

How many CPU or vCPU and how much memory? Also, what is the threshold of users when the system reaches these levels (20, 30, 50 users)?

Also, do you have CPU and/or memory management turned on?

Looking through the technotes it appears that this software is, and always has been a resource hog on terminal servers.

There are some docs alluding to the fact that as few as 10 sessions can be run with it.

Why did the points go to someone who only told you where to find what I'd told you to do? Surely it was my solution?
