BcacheFS vs. EXT4 vs. Btrfs vs. XFS vs. F2FS

Yesterday I posted the first independent benchmarks of the Bcachefs file-system, the new file-system aiming for EXT4/XFS speed while having Btrfs/ZFS-like features. Here are some more benchmarks.

Complementing the benchmarks from yesterday are some more results today with Bcachefs compared to EXT4, Btrfs, XFS, and F2FS with testing being done from the same Intel M.2 SSD as yesterday's testing and using the same 4.1-based Bcachefs-dev kernel.

If you want to see how Bcachefs compares to these four other open-source, in-tree Linux file-systems, you can find the new results via this OpenBenchmarking.org result file. Enjoy!

I also was going to test the Zlib compression support but ended up finding no performance difference. I have been in communication with Kent Overstreet and afterwards he ended up exposing some compression stats via sysfs to benefit future tests.
