Oh, I tested ext3 vs. 3ware RAID5 in *multitudes* of configurations -- all 
3 different journaling configs, external journals, various size journals, 
etc.  Nothing helped.  There's just some bad juju there.  On the same 
hardware, XFS and even ext2 pulled far better than numbers than ext3. 
Put the 3ware in RAID10 (or use md), though, and ext3 worked just fine 
with it.

Trust me, it wasn't for lack of trying.
