For these tests I stuck to my 3 favourites, JFS (from IBM), XFS (from SGI) and ZFS (from Sun, ported to Linux using FUSE by Ricardo Correia due to Sun’s GPL-incompatible license). This is a follow on from a slew of earlier ZFS & XFS benchmarking I did reported on previously (( here, here, here and here )).
Summary: for Bonnie++ JFS is fastest, XFS next fastest and ZFS slowest and Feisty made XFS and ZFS go faster (didn’t record my previous JFS results sadly).
The fact that ZFS is slowest of the three is not surprising as the Linux FUSE port hasn’t yet been optimised (Ricardo is concentrating on just getting it running) and is also hampered by running in user space. That said it still manages a respectable speed on this hardware and does have useful functionality that makes it useful to me.
