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.
Initially, this disk was formatted with ext3. However in time, I got
to the point where the data rate when reading from disk was not enough
to sustain a CD/DVD writing process. I switched it to XFS, but did not
initially run xfs_fsr on a regular basis and this also started to
behave the same after some time. After enabling xfs_fsr (nightly run),
the reading speed is back to normal and the CD/DVD writing works fine.
This is now in use for more than 2 years and I never looked back...
