    Phoronix: Btrfs Enjoys More Performance With Linux 6.3 - Including Some 3~10x Speedups

    The big batch of Btrfs file-system driver updates for the Linux 6.3 kernel were submitted today by SUSE's David Sterba. As with many kernel cycles, this Btrfs pull includes more performance optimizations as well as new features...

    Very nice. I wish steamOS used BTRFS.

      I like (and use)BTRFS but for games it's better with ext4

        How so? I use SteamOS-BTRFS which has been working very well for me so far.

          btrfs doesnt support casefold. so ext4 is better for wine/proton

            Interesting, better in what way? I would expect ext4 to be better for databases and VMs (lots of random access writes, which never goes well with CoW), but what is it in games behaviour that make it better>

              Someone correct me if I'm wrong, but IIRC, the biggest two gaps for BTRFS that made EXT4 the default were:
              1. Allowing case sensitive insensitive directories / Filesystem (used by Wine in some cases)
              2. Performance


              I don't know to what extent these are/were true and whether 6.3 and later will close these gaps.

                Ext4 still outperforms BTRFS. I'd like to see some benchmarks to see the recent speed difference with kernel 6.2 and 6.3-rc1(when it's out)

                  Well the features of btrfs does not come for free so ext4 will always outperform btrfs. And honestly the features of btrfs is kinda lost on games from Steam since Steam calcs it's own checksums and can just download corrupted files anew.

                    I'd like to know which one is faster with recent SSDs and striping, e.g. BTRFS-RAID0 or md-RAID0+ext4.
