This guy is having a problem with cyrus-imap and ext3 - when multiple
processes are attempting to write to the one filesystem (but not the one
file), performance drops to next to nothing when only five processes are
writing. An strace shows most of the time is being spent in fdatasync
and fsync.
Actually, the thread just got off topic quickly -- I'm running this on reiserfs,
not ext3. ...And I've got it mounted with data=writeback, too. But thanks for
the info, Andrew.

I'll bet that the fakesync preload library will make diference for you.
