"Mike Benoit recently posted a link to results from his new and
improved file system shootout, using better hardware and running
more tests. Using two benchmarks that are designed to measure hard
drive and file system performance, Bonnie++ and IOZone, he's
compared a number journaling filesystems found in the 2.6 kernel.
Included in the lineup are EXT2 (not journaling, but an effective
baseline [story]), JFS, XFS, ReiserFS, Reiser4, and EXT3 each
compared head to head on both SCSI and IDE drives.
"In Mike's summary he labels JFS and XFS as 'best bang for your
buck' explaining, 'While not the fastest file systems, both of them
consistently perform close to EXT2, while using minimal CPU. XFS
seems to be faster over a wider range of benchmarks, however it
does use slightly more CPU than JFS. While JFS really starts to
slow down with lots of files.' As for pure speed, Mike points to
Reiser4 which really shined in the Bonnie++ benchmarks, though not
quite so much in the IOZone benchmarks. He suggests, 'ReiserFS v4
will [definitely] be worth while keeping an eye on, especially
considering some of the exciting new features it offers...'"
