    Linux 4.3 File-System Comparison With Btrfs, EXT4, XFS, F2FS

    Phoronix: Linux 4.3 File-System Comparison With Btrfs, EXT4, XFS, F2FS

    Last week I posted some fresh Linux file-system tests on a hard drive but for those preferring solid-state drives, here are some fresh benchmarks. Tested for this comparison were Btrfs, EXT4, XFS, and F2FS from an SSD while running with the Linux 4.1, 4.2, and 4.3 kernel releases.

    Dear sir! As a reminder, typical male recognizes ~16 colors (and peach is g*d d*mn fruit). Colors on plots for XFS and F2FS are really not very distinguishable.Still, a great article.

    I'm a bit amazed by both F2FS performance and BtrFS mis-performace... Worth a shot to try Ubuntu on F2FS (on a spare disk of course )

      Why the hell, no matter how much time passes, Btrfs stays slow and ext4 stays fast?

        Oh I dunno... Maybe because ext4 is a traditional journaled filesystem, and btrfs is a Copy on Write filesystem?

          Two lines are blue and two are red - is that what you see

            Lines, what lines?

              Why is the autodefrag mount option never used for btrfs? It has been a mount option since forever, and is recommended for systems with lots of random writes.

                BTRFS is a copy on write filesystem, and incorporates the functionality of MD RAID-like behavior and LVM2 volume management into the filesystem. In addition, BTRFS checksums the data as well as the metadata, so corruption can be identified and corrected (if running RAID1 or DUP, for example).

                  Why without ZFS?!

                    so performance ordered:
                    btrfs - bad
                    xfs - good
                    ext4 - better
                    f2fs - the best
