Measuring disk I/O

Posted on 2011-05-11

I have a command that I plan to run on a MS Exchange 2007 server running on Windows 2008 Server.

I'd like to measure the resource hit this has on Exchange in terms of the following - I/O, CPU, and memory.

I guess for CPU I just measure the Processor counter in Perfmon, but does anyone know the best counters to measure memory impact and disk I/O caused by this?

Many thanks!

    SQLIO is a very popular disk IO measurement tool. It’s free and can be downloaded from here:

    And a small tutorial:

    CPU and memory are more difficult to measure because their usage depends on the quantity of mailboxes and messages that will traverse the server. I suggest you to follow the System Requirements guidelines from Microsoft:
