Outside more up-to-date question, here is my own experience with jfs/xfs.
The bigger the files with JFS, the slower it is.
XFS tends to get similar performance, whatever the filesize is.
I've had data corruption with both. The thing is, I don't know where
it comes from with JFS, with XFS *do* *not* *ever* run a box without
an UPS. Unclean shutdown will always eat some of your data.
I've been happy with ext3 (no data corruption ever happened) but its
speed is behind the first two.
Hope this helps,
Laurent
