    Default Linux 3.16 File-System Tests On A Hard Drive

    Phoronix: Linux 3.16 File-System Tests On A Hard Drive

    In complementing the earlier Linux 3.16 file-system tests on an SSD (and the later Btrfs testing), here are benchmarks of EXT4, XFS, and Btrfs from the Linux 3.15 and 3.16 kernels being compared from a traditional rotating hard drive.

    I can personally confirm that ext4 does feel pretty snappy on 3.16rc4 on my HDDs, but it's nice having some benchmarks to also back up that statement

    Default Elevator

    Did you use the elevator=deadline kernel parameter with XFS, as recommended? The default CFQ elevator does not work well with XFS. Setting elevator=deadline or even elevator=noop should provide better performance.

    Do you have any links regarding that recommendation? (XFS user here).

    Btrfs seems to be neck and neck with Ext4, actually beating it in the most realistic benchmarks (kernel compilation and dbench). This seems to be a pattern on hard drives, while Btrfs does more poorly on SSDs. I'd rather have this than the other way around, because SSDs are here to stay and much more effort will be put into making optimizations for SSDs in the future. Now if Btrfs can only get ahead in the other, more synthetic, benchmarks...
