One tunes filesystems the hard way or not at all. You either accept the
defaults or do a detailed performance evaluation. It's actually not all
that hard ... figure out what your workload is and benchmark it over all
half-dozen or so major supported filesystems (XFS, JFS, Reiserfs 3,
ext2, ext3 and a couple others I've forgotten). Then when you have a
winner, tune that filesystem.
