This screenshot is the only metric where btrfs is incredibly slow.

Bcachefs random and sequential writes and reads are much slower than other filesystems in this benchmark.

I have no idea how the actual real world performance will be. Bcachefs still misses a lot of features so I’ll continue to follow the development, hopefully including performance improvements.

Bcachefs sequential write performance in this out-of-the-box comparison was coming in at around half the speed of Btrfs while XFS, F2FS, and EXT4 were the fastest.

Edit: The benchmarks were done with a debug variable set, which explains the weak IO.
