If anyone happens to know a command-line capability or version of iozone,
please let me know... tons of NT benchmarking I could automate the
hell out of once I find it :)

Yes, please! :) tiotest sprung up specifically for s/w raid testing
(though it's not specific to that, at least not yet :) and the more
pounding we can do, the better.
Feedback about USE_MMAP in tiotest and whether it causes any significant
changes is also very desired.
I'm hoping Linus will finally accept Chuck Lever's mincore() (and later,
madvise()) patch, solely so we can possibly get to the point where we
can efficiently benchmark without caching effects. This is currently,
IMHO, the weakness in all methods of Linux i/o benchmarking...
