    Default Ubuntu Unity Proves Very Slow To KDE, GNOME, Xfce, LXDE

    Phoronix: Ubuntu Unity Proves Very Slow To KDE, GNOME, Xfce, LXDE

    Earlier this week when benchmarking the latest Unity and Compiz packages for Ubuntu 12.10, I mentioned a new OpenGL desktop comparison was forthcoming. Those results from the Ubuntu 12.10 development snapshot are now available with the default Unity desktop being compared to KDE, GNOME, Xfce, and LXDE. In no test did the Unity desktop yield the fastest performance with nearly every time the default Ubuntu desktop being left in last place for performance.

    I guess that suspention of KDE doesn't work with a dual-monitor setup?

    KDE works flawless with Dual-Monitor: my System http://www.sysprofile.de/id123113.

    Default Why?

    Why are some faster and slower than others?

    I'm curious about the effect of "Undirect fullscreen windows" option for compiz, I think it would be interesting to see its effect(and possibly a couple more options that could improve performance, basically disable "Sync to Vblank" and "Detect framerate", also inserting the appropriate value for the framerate on the same page).
    I know that the tests performed here were mostly meant to test default configurations, but I'd be interested to see this tested as well. I've noticed that this option can cause some bugginess .. So is it worth it?

    And so .. Was anyone saying KDE is heavy and slow and that XFCE is better for performance/gaming etc?


    Edit: Should have also said .. Thanks for the benchmarks, it's good to have those comparisons.
    (Although I'm also curious if different hardware[graphics card] causes significant changes)

    Wasn't L4D2 faster on Ubuntu than on Windows?
    Didn't that Ubuntu use Unity? [http://blogs.valvesoftware.com/linux.../#comment-4328]

    Just imagine a "KDE SC 4.9 - Suspended" so much more frames per second

    Actually, Xfce has a fully supported and configurable compositor, it is just not on by default. On 4.8 it can be toggled from the "Window Manager Tweaks" settings option under the "Compositor" tab. From there you can also tweak the compositor effects and also specifically set the compositor to "Display fullscreen overlay windows directly". Considering you took the time to tweak KDE for this benchmark, I would appreciate it if you would also do the same for Xfce in future tests.

    Exactly. I'd love to see benchmarks with KDE compared to OS X and Windows.

    Default Unity's no good

    Interesting results, especially KWin fullscreen compositing vs fullscreen suspended. Compare this with the Phoronix results published earlier showing that with the Catalyst drivers give the same performance, fullscreen compositing enabled or not. What does this say about the Catalyst and Intel drivers? I guess performance should be the same whether or not compositing is enabled, non?
