We use ext3 because it's mainline, supported, and I simply don't
trust the
other file systems to have had sufficient real-world testing and
sufficient attention paid to recovery tools.
I care more about file system consistency and reasonable recovery from
hardware and software failure than I do about the last iota of speed.
We used to use XFS on linux as well -- though with the performance
differences you have noticed, I'd be interested to see the benchmarks
on XFS with/without an fsync'ing volserver & fileserver. Those can
be pretty fsync() intensive operations, and that could be where XFS
is falling down. We had a couple fileservers that we were running
ext3 on for awhile as well, never had any problems with them to
complain about.
Right now we're a Solaris/ZFS shop, which isn't without its
problems. However, its been amazingly stable/resilient/easy to
manage -- which is where I think Linux + whateverfilesystemyoumention
falls down. Sometimes that can be just as important as raw performance.
