I've had the chance to use a testsystem here and couldn't resist running a few benchmark programs on them: bonnie++, tiobench, dbench and a few generic ones (cp/rm/tar/etc...) on ext{234}, btrfs, jfs, ufs, xfs, zfs.
All with standard mkfs/mount options and +noatime for all of them. Here are the results, no graphs - sorry: http://nerdbynature.de/benchmarks/v40z/2009-12-22/ Reiserfs is locking up during dbench, so I removed it from the config, here are some earlier results: http://nerdbynature.de/benchmarks/v40z/2009-12-21/bonnie.html Bonnie++ couldn't complete on nilfs2, only the generic tests and tiobench were run. As nilfs2, ufs, zfs aren't supporting xattr, dbench could not be run on these filesystems. Short summary, AFAICT: - btrfs, ext4 are the overall winners - xfs to, but creating/deleting many files was *very* slow - if you need only fast but no cool features or journaling, ext2 is still a good choice :) Thanks, Christian. -- BOFH excuse #84: Someone is standing on the ethernet cable, causing a kink in the cable -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
