I use ext3, but for reliability and not performance.  XFS really sucks
for reliability, though it is supposed to be fast.  In my opinion, XFS
is more trouble than it's worth.  If you insist on other fs, Reiser is
a better choice.  I don't have any experience with JFS, but I don't
believe it is as mature as Resiser.

As long as the boot partition is ext2, you can pretty much run anything.
You can get into situations though where the system won't boot at all,
requiring moving the drive to another machine to recover, but this is
quite rare.
