Do you care more about performance? Or reliability?
I think I'd rather see things 3% slower than they could perhaps be if
that diminishes the risk of suddenly losing a filesystem...
The last time I did a benchmark, I found JFS *slightly* faster than
XFS, and XFS slightly faster than ext3. But then lost several JFS
filesystems to weird interactions between JFS and disk controller.
That was about 2 years ago; there have been new releases of both
filesystems, SCSI device drivers, as well as major kernel revisions.
It's not evident how much things have really changed.
At any rate, I would NOT put filesystem performance at the top of the
list; ability of vendors to provide support is something I would put
much higher. That factor alone usually rules out both JFS and XFS...
