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.
Good cause in some technical parts Unity is bad (it copies existing Apis and just rename them like with Unity.MediaPlayer and Mpris) just look at Unity APIs and for the most parts you'll find an equivalent at freedesktop.org.
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)
Seems like the answer is obvious. Copy what KDE did. KDE with effects on is nearly identical in performance to Unity without fullscreen mode on, but it performs on the level of uncompositied desktops when using full screen mode.
Unity should just implement what the KDE group did. Seems to work.
