G'Day Folks,
FileBench looks great. I've been wanting to write such a tool for a while,
but this is far more comprehensive than I was planning. :)
Apart from it's own output, which is terribly useful, I've been using
it to generate test load for other tools:
random uncached 8k reads:
$ iostat -xnmpz 1

Cool!
...
Imagine using this for a practical Solaris interview. Create a well
defined testload with filebench, then ask the applicant to describe the
filesystem activity using existing Solaris tools (without reading the
filebench profile... Just need a CPUbench, Membench and Netbench as
well... benchbench?... :-)
thanks for releasing this!

PS. Ok, maybe the TTCP and pathchar varieties serve as a form of Netbench.
