A New Linux File-System Aims For Speed While Having ZFS/Btrfs-Like Features

The performance of Bcachefs in many of the non-Dbench tests were noticeably slower than EXT4 and Btrfs. However, Kent Overstreet mentioned there still is much performance tuning/optimizations to be done.

It will be interesting to see how Bcachefs compares to F2FS and XFS, which will be done in the follow-up article when more time has been spent on testing and perhaps with some other hardware too.

On a related note, you may be interested in my recent six-way Linux file-system performance test from the Linux 4.1 kernel.

Given that it's building upon the BCache block layer cache, Bcachefs should be a rather interesting file-system project to monitor. It will be interesting to see how it's able to perform in the long-run and how much adoption/support it will receive in the already saturated field of Linux file-systems. Many have been waiting for years for Btrfs to become the default "next-gen" Linux file-system but we still have yet to really see that day, but maybe we'll finally see that happen in the next year or two. Stay tuned for more tests of it and the other Linux file-systems on Phoronix in the near future.
