The final FS-Mark test used was of 4,000 files spread across 32 sub-directories. F2FS was again the fastest with no other interesting findings to note.

For the Dbench test profile, F2FS was by far the fastest file-system, but based upon the reported speeds, the file-system wasn't syncing to the disk like the other file-systems. Between the others, Btrfs is now the fastest file-system for this Dbench configuration on the standalone SSD except there is a noticeable performance drop for Btrfs between Linux 3.9 and 3.10-rc1. The EXT4 and XFS performance was flat-lined between Linux 3.8 and 3.10 for the Intel solid-state drive.

The IOzone read performance isn't terribly interesting aside from the Btrfs performance having regressed after the Linux 3.8 kernel release.
