Testing The "Pretty Beefy" Btrfs Changes In Linux 3.2
The FS-Mark test of touching 1000 files of 1MB size each is slightly faster under the Linux 3.2 kernel.
When performing the same FS-Mark test but not forcing sync/fsync calls, there is not much of a change in performance.
When dealing with concurrent disk writes, Btrfs in Linux 3.2 appears a bit faster.
