"dbench 64, 128, 192 on ext2fs. dbench may not be the best I/O benchmark,
but it does create a high load, and may put some pressure on the cpu and
i/o schedulers. Each dbench process creates about 21 megabytes worth of
files, so disk usage is 1.3 GB, 2.6 GB and 4.0 GB for the dbench runs. Big
enough so the tests cannot run from the buffer/page caches on this box."

Thanks kindly for the testing, but please don't use dbench any more for
benchmarks. If you are testing stability, fine, but dbench throughput
numbers are not good for much more than wild goose chases.

Even when mostly uncached, dbench still produces flaky results.
