multi processor issue

[Cathy_db]

Hi,

How can I check if in our .net environment the applications are using
all 4 of our processors ( 2 CPU's hyperthreaded)
The issue is that our test environment with 1 CPU (hyperthreaded) shows
better performance then our production environment which has two
hyperthreaded CPU's.
We are pretty sure it is not a hardware issue, but probably some
misconfiguration or missing setting in the applications. I think the
application is not using all 4 processors. How can I monitor the .net
application and processor usage.

You will have to use performance counters to analyze processor usage.
Take a look at

I guess we should ask the obvious questions first. Does your
application take advantage of multithreading? Other than the number of
physical CPUs are the hardware configurations the same?
