Ubuntu 12.04 LTS - Benchmarking All The Linux File-Systems

When not enforcing any sync/fsync requests with FS-Mark, the numbers are obviously all much closer.

Running four threads of 5000 files of 1MB size with FS-Mark, the numbers were also close, but EXT4 ended up being the fastest of the leading three Linux file-systems.

With the final test of FS-Mark doing 4000 files in 32 sub-directories, XFS sprung well ahead of Btrfs and was slightly ahead of EXT4. JFS also was performing surprisingly well in its stock configuration on Ubuntu 12.04.
