At the time, I had a long discussion about it on nahant-list (see the embarrassingly titled thread that starts here https://www.redhat.com/archives/nahant-list/2005-October/msg00271.html) with no resolution. And I brought it up again on the ext3 list in April.
It seems that some of the "performance sucks" feeling should actually be directed at the 3Ware RAID adapter that is common in those threads rather than the filesystem.
Except for the fact that other FSes on the same hardware get far better performance. These were my results using 2 7506-8 boards, each in hardware RAID5 mode, with a software RAIDO on top:

Joshua,
Did you do any other tuning to get the ext2 numbers? I have two 7506-4 boards that I can only seem to get 13/117 out of.
