Linux 3.13 Kernel HDD File-System Benchmarks

Btrfs delivered the fastest performance in the Threaded I/O Tester when dealing with 32MB and 64MB linear writes using four threads, but its performance had regressed slightly under Linux 3.13.

Btrfs delivered the best performance still in Threaded I/O Tester when involving random writes, but when doing four threads of 32MB per thread, the performance had dropped under Linux 3.13. The EXT4 and XFS performance was largely unchanged between Linux 3.12 and 3.13 kernels.
