Linux 3.12 Kernel To Bring Faster File-Systems

For the last FS-Mark test, when dealing with multiple sub-directories, there were performance improvements across the board for all four file-systems on the Linux 3.12 kernel. The improvements were quite noticeable in this disk benchmark and F2FS overall was doing the best from the Intel SSD on the Haswell ultrabook.

The Dbench test also saw nice file-system performance improvements across the board for EXT4, Btrfs, XFS, and F2FS. The fastest overall was still the flash-optimized F2FS from Samsung.

The CompileBench compile test saw a huge jump in performance on Linux 3.12 for Btrfs while the other changes were less noticeable. For this test, XFS, Btrfs, and EXT4 were performing in the same range now while F2FS was the slowest.
