Last week we tested four Linux file systems — ext3, ext4, nilfs2, and btrfs — for metadata performance using a benchmark called fdtree. The point of the benchmarks was not really to comparison the performance of the file systems per say, although comparisons are inevitable. Rather, the benchmarks were performed as part of an exploration into the metadata performance of Linux file systems.

We‚Äôre using the same benchmark from the last article and applying it to additional Linux file systems – xfs, jfs, reiserfs, ext2, and resier4. As you are probably aware there are a large number of file systems available in Linux from some fairly old ones such as ext2, to some that are still considered ‚Äúexperimental‚Äù in the latest kernel (2.6.30 as of this writing) such as btrfs and nilfs2. But these other file systems, ext2, xfs, jfs, reiserfs are still in production use in a number of places…
