Bcachefs Linux File-System Benchmarks vs. Btrfs, EXT4, F2FS, XFS

First up was the SQLite embedded SQL database library test. On the HDD the Bcachefs performance was just behind EXT4 but doing much better than Btrfs though not nearly as fast as XFS in this case. On the SSD, Bcachefs came in behind EXT4 again but faster than Btrfs while XFS and F2FS were the fastest for SQLite on this consumer-grade SATA SSD.

In sequential read performance, Btrfs and Bcachefs were terribly slow on the HDD while on the SSD Bcachefs was the slowest, just behind XFS while Btrfs and F2FS were competing for the top spot.

In the sequential write test, Bcachefs again was just competing with the copy-on-write Btrfs file-system.

In FS-Mark at least this new Linux file-system was still slow on the SSD, but at least not too far behind, while the hard drive performance in this test was similar between file-systems.

With four FS-Mark threads running on the respective disk, Bcachefs was faintly slower than the rest on the HDD while the SSD performance was similar across the five tested file-systems.
