Did you try data=journal mode on ext3? For real-life workloads sync-IO
workloads like mail (e.g. not benchmarks where the system is 100% busy)
you can have considerable performance benefits from doing the sync IO
directly to the journal instead of partly to the journal and partly to
the rest of the filesystem.
The reason why "real life" is important here is because the data=journal
mode writes all the files to disk twice - once to the journal and again
to the filesystem, so you must have some "slack" in your disk bandwidth
in order to benefit from this increased throughput on the part of the
mail transport.
