I am currently engaged in a "bake-off" of sorts between two different
vendors. We used IOzone as an initial test, but picked three of our most
representative codes to do the remainder of the tests. With these codes we
scaled up the number of concurrent processors, the number of files, and the
file size, including parallel and single node writes and reads.

As always, the best test is your own code.
