    multi processor issue

    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
    misconfiguratio n 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

      Additionally

          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?
