  • File System Benchmarks in Linux

    As Michael requested: a suggestion for Linux benchmarking:

    I would really like to see some file system comparisons next time you
    test a (stable) Linux kernel. Benchmarking Linux kernels is fine, but aside from the new features, significant performance gains are unlikely (especially when testing with games). It seems we know much less about the performance of the array of Linux file systems we have. The last good file system benchmarks I saw were fefe's: http://bulk.fefe.de/scalability/, but it seems he's ceased his testing.

    I know it is difficult to control file system benchmarks in a fair way, but the guidance within fefe's extensive tests should surely get you started. I'd like to see reiserfs3, reiserfs4, ext3, ext4, xfs, jfs, and zfs in a line-up. I have lots of ideas so please reply with any questions.

    Funny, you should mention filesystem tests:

    Smaller is better:

    Code:
     -------------------------------------------------------------------------------------------------
    | Filesystem | Copy Sources | Disk Usage | Copy Sources | Tar & Gzip | Untar & Unzip | Delete All |

    | XFS        |          221 |        799 |          173 |        120 |            91 |         57 |

    | EXT2       |          204 |        816 |           81 |         73 |            40 |         24 |
    | EXT3       |          181 |        816 |           77 |         77 |            46 |         26 |
    | FAT32      |          252 |        988 |          162 |        126 |            88 |         19 |
     -------------------------------------------------------------------------------------------------
    REISER4 wins (by far) in ALL the important categories.

    It is not clear why NTFS preformed so poorly.

    Everyone knew FAT32 was a dog.

    The reiser4 filesystem clearly outperforms all the other filesystems, in almost all the measured categories. Using reiser4, rather than ext3, saves you a massive 816 - 692 = 124 MB of disk space (a 15% saving, mainly, from eliminating block alignment wastage). Not only do you save 124 MB, but your copy is finished significantly quicker.

    As you can see, REISER4 is a truly remarkable filesystem.

    This is the real reason that REISER4 has not been included in the Linux kernel.
    This is the real reason that Hans Reiser languishes in an Oakland prison cell at this time.

      Thats excluding ext4 and zfs. If the phoronix people get around to testing newer versions of these with a newer kernel...That would be cool.

        Jade: you also forgot to mention that Reiser4 is unstable as hell. Sure, it performs nicely, no doubt about that. But would you really trust your data on a fs that can f*ck itself over any second? Not me, thanks.

          I was thinking the same thing. It's fast, maybe because it doesn't handle thing securely. I'd be interested in seeing ext4 performance as well.

            Reiser4's performance is awesome. I'd use it if its latency was better and it was stable.

            No. Reiser4 has it's own built in replacement for kernel code that the other linux filesystems use. That replacement would be redundant - the kernel devs would rather reiser4 and the other file systems share as much code as possible. They also said it was too unstable. That's why.

            Name one person/entity with the motive to do what you're implying. Let me guess - it's gotta be either Elvis or Big Foot, right? No wait, it's probably that massive government conspiracy with the aliens. Reiser4 protects you from being kidnapped and probed, and they can't have that can they?

              May I politely suggest that you are mistaken.

              If not, please produce the studies that show the purported Reiser4 instability.

              I have seen ZERO evidence that Reiser4 is unstable.

              I have noted that Reiser4 has been deliberately sabotaged in all of Andrew Morton's recent Linux kernels (linux-2.6.20-rc1-mm1 thru rc4), and even though many complaints can be found on the internet, no one has bothered to respond to, or fix, the problem(s).

              StringCheesian said: "Name one person/entity with the motive to do what you're implying."

              Hans Reiser is a Jew who is being slandered and set up by Jews.

              His problem is that his product Reiser4, is much better than NTFS.

              This is a problem for Microsoft and Microsoft owners.

              The visible face of these people is "the Jews" (the secret society, not the religion, or having a Jewish mother (although, of course, the last are closely related to the first)).

              The GPL prevents the usual tactic of buying him out (and turning Reiser4 into NTFS2).

              Without the GPL, Reiser might be a rich man, and Microsoft might be extolling the virtues of it's new filesystem.

                Jade,

                I have already warmed you about your anti-semitic remarks on the Phoronix Forums. These comments will not be tolerated and any further rants will result in your banning on the forums. I ask that you kindly refrain from making these comments, thank you.

                  This is unbelievable. Did anyone ever see that Mel Gibson movie where he was worried everyone was watching him, and he had his house locked down and had all the conspiracy theories? Can't remember the name of the movie (probably Conspiracy something or other), but Jade missed his calling.

                  Stop posting this crap here... find some foil collector's community to work out the details of your as-yet-to-be discovered plot for Jewish world domination.

                    It's Conspiracy Theory.
