Does anyone have any benchmarks for the XFS filesystem contrasted with
the amount of fragmentation on the disk?
Not real benchmarks (which could be too specific), but a real world
situation. I have at home a computer with a large PATA disk with XFS on
it. This disk receives small amounts of data in time, from video encodes
(own home productions and I like to experiment with filters a lot so
data rate could be really low) or P2P applications (like recently from
FC5 and CentOS 4.3 DVDs), either directly (run on the same computer) or
via Samba.
FWIW, many P2P applications will -horribly- fragment the downloaded
files, as the chunks of the file come in randomly. Try to find one that
is smart enough to use pre-allocation on xfs filesystems, and you should
see a marked improvement.
