    Default CentOS 5.4 vs. OpenSuSE 11.2 vs. Ubuntu 9.10 Benchmarks

    Phoronix: CentOS 5.4 vs. OpenSuSE 11.2 vs. Ubuntu 9.10 Benchmarks

    With the release of CentOS 5.4 last month to bring this community enterprise operating system on par with Red Hat Enterprise Linux 5.4, we decided it was a good time to see how the server / workstation performance between this new CentOS release compares to that of Ubuntu 9.10, which was released last week, and also how it performs up against the release candidate of OpenSuSE 11.2. In this article are these benchmarks.

    Can you please list which kernel you were using for the server/workstation benchmarks for openSUSE 11.2?

    There are two flavors,

    -desktop (which is optimized and configured for desktop use)
    -default (which optimized and configured for workstation/server use)

    By default openSUSE 11.2 will install the desktop kernel so unless it was changed from the default install you would have had the 2.6.31-desktop kernel installed when running your tests.

    Guys,

    PLEASE start filing (regression) bug reports in http://bugzilla.kernel.org/ otherwise your tests are worth nothing.

    Also,

    OpenSuSE 11.2 RC1 runs with the Linux 2.6.31 kernel, GNOME 2.28.0, X Server 1.6.5, NVIDIA 190.29 display driver, GCC 4.4, and uses the newer EXT4 file-system by default.
    This isn't true, the default desktop is KDE 4.3.1. Gnome is a selection though.

    Actually that's not phoronix's job, that is the responsibility first of the distro's community to see if it is truly a kernel regression or a misconfiguration as their configs vary distro to distro. Regressions should only be submitted when running a generic kernel and most distro's do some customization to the kernel and do not use the same configs. If it is found that it is actually a kernel regression then the distro can always send it upstream.

    You might also want to disable AppArmor in the future as well since you disabled SELinux on CentOS and gives it a bit of an advantage.

    Default sqlite

    So, on what kernel version and file system does sqlite not get bogged down?

    I'm planning to do a clean install of 9.10 Ubuntu server and sqlite will be used frequently on that.

    I have upgraded one of the machine to use 9.10 server from 9.04 server, which kept the ext3 partition but the phoronix-test-suite went pretty slow on sqlite afaik, something like 150 seconds per test on a ssd with 120+mb/s read and probably half that for write.

    What fs modes do those distros use? If CentOS uses writeback and other use ordered it probably can explain such difference in SQLite.

    openSUSE uses barriers enabled, file extents enabled, delayed allocation enabled, mballoc enabled, ordered data mode. internal journal by default on ext4.
