You can try fsbench which is not a generic benchmark. However, you
mention Postgres DB so it may or may not be useful to you. fsbench
simulates delivery to a maildir and simulates a single writer/reader to
16 writers/readers. Of course, it uses fsync calls unlike certain
benchmarking software that do nothing of the sort like postmark. If you
need a copy of fsbench, I have the original tarball that Bruce Guenter
published.
