    Phoronix: X.Org vs. XMir On KDE, Xfce, Unity Desktops

    The latest interesting Linux test results to share this week for those not at Oktoberfest are 2D and 3D/OpenGL benchmark results when testing XMir and a pure X.Org Server configuration with the Xfce, Unity, and KDE desktops as will be found in next month's Ubuntu 13.10 release.

    What's more interesting that XMirs performance hit
    is the huge performance hit by KDE.
    It's up to five times slower than Unity which runs Compiz!

    How the heck can it be that slow?

    Default XWayland

    I would have loved to see XWayland thrown into the mix.

    I think you should also benchmark app version that communicate with Mir/Wayland directly
    As there also exist Qt for wayland and QT for Mir , gtk for wayland

    Not possible because XWayland works on a rootless X environment while current XMir is the opposite

    while for wayland you have weston and some other desktop environments been port to it, for Mir Unity 8 isnt ready yet so theres no easy possibility of testing that.

    For intel, Xmir uses sna, whereas XWayland uses uxa. Results are therefore predictable for these X drawings benchmarks.

    Wait for a glamor backend for XWayland (that would work on all cards), and the results will be more interesting.

    Previously people have blamed Oxygen style for KDE performance issues:

    Oxygen rendering path is much more complex than qt curve, due to gradients, animations, etc.
    It is therefore expected to be slower and this does not make it a bug. It is your call to decide between performances and features
    Also note that nvidia (or rather, at least some of the versions of the linux drivers) are known to behave badly with respect to cached pixmaps, which oxygen does alot (as opposed to QtCurve), in order to "improve" performances on other graphics card (and other drivers). Not much we can do about this.

    Now there is essentially no reason not to use XMir, other than driver support for EGL from AMD and NVIDIA. The benefits from using XMir instead of X are good enough reason to ditch X for now.

    you do realise you need the x-stack to allow x-mir and x-wayland to do their thing ... ? :P

    you'll be looking at black screens if you ditch X!
