This is a snapshot of a typical performance monitoring session I use to track down performance issues or review the system at any given point.

SQL and System Performance Counters

There are a lot of other scripts out there that are available and even an SQLIO GUI.  Here are a few I looked at myself.

SQLIOToolSet
SQLIO GUI (screenshot)
SQLIO.Scripts

My script is a basic DOS batch file that automates collecting statistics on a few different drives when you’re testing.  You need to make sure you have created the %TESTFILE% on the root of the drives you want to test.  I create, and I suspect most others do as well, a testfile.dat on the root of each drive I test.  You’ll need to create this before running the script or it will break!

If you want to extend this script, it’s easy.  All the testing is put into a function called RUN_BENCHMARK which is called and passed a drive letter argument.  So if you want to add more tests, feel free.  Just mimic the existing code in that stanza and you should be ok.
