For the I/O 4K random read performance when using the modern IO_uring interface, NILFS2 / F2FS / XFS were effectively tied for first followed by Btrfs and then EXT4 in a distant last place.

Switching over to random writes, XFS led the race followed by F2FS and EXT4 while Btrfs was a bit behind those three. NILFS2 here was by far the slowest.

F2FS was the fastest for the sequential read performance with IO_uring.

XFS followed by Btrfs in a close second were the fastest for sequential writes.
