Btrfs File-System Mount Option Testing From Linux 3.14

The synthetic IOzone test obviously benefited from Btrfs' transparent file-system compression feature due to its easily compressible data.

CompileBench was also a winner with Btrfs compression support while the discard support led to the file-system performance being reduced.

Lastly for the PostMark workload the Zlib compression and no data copy-on-write mount options led to the greatest performance improvement.

More details on the Btrfs mount options can be found via the Btrfs Wiki. You can easily run your own automated disk benchmarks on the disk workloads relevant to your purposes via the open-source Phoronix Test Suite.
