When kicking things off with FIO and performing some 4K random writes, Bcachefs out-of-the-box was much slower than the other tested Linux file-systems at their defaults including other CoW file-systems like Btrfs.
4K random reads were much slower on Bcachefs.
The sequential read performance meanwhile wasn't quite as bad with Bcachefs but still trailing the other more mature file-system options form this Solidigm PCIe 4.0 NVMe SSD.
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.
