It really depends on what you're doing.

Actually, yes!  If your server has a UPS, and will automatically do a
clean shutdown on power failure, then you should try ReiserFS, XFS, and
ext3 under the workload you're expecting.  If you don't _know_ what your
workload is, then try using bonnie++ to get an idea of the performance
characteristics of your filesystem and disk IO subsystem.

If you server is _not_ going to have a UPS, then you're pretty much
stuck with ext3, for the reasons detailed here: 


You should still benchmark, though, if you care about performance; there
are quite a few IO tuning parameters that can have positive effects on
system performance (for example, changing the IO scheduler can affect
database hosts positively).

If you don't care about performance enough to benchmark, then I'd say go
with ext3: it's the default and is well tested.
