EXT4, Btrfs, XFS & F2FS On Linux 4.6 Through 4.9

Interestingly for the BlogBench read test, EXT4 is noticeably slower than the other tested file-systems.

But for write performance, EXT4 is on top with BlogBench while XFS was in last place.

EXT4 was in front for CompileBench while Btrfs fell to last place.

PostMark isn't the most reliable disk benchmark and is fsync happy, but for this case anyhow F2FS came out in front.

Those wanting to dig through more of this performance data can see this OpenBenchmarking.org result file. Overall, not too many surprises. I'll be adding in Linux 4.10 data points once the merge window closes. I'll also be doing some more tests shortly with Linux SSD NVMe storage.
