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: http://www.microsoft.com/downloads/en/details.aspx?familyid=9a8b005b-84e4-4f24-8d65-cb53442d9e19&displaylang=en

And a small tutorial: http://sqlserverpedia.com/wiki/SAN_Performance_Tuning_with_SQLIO

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: http://technet.microsoft.com/en-us/library/aa996719%28EXCHG.80%29.aspx
