I've installed Unity from the SRU PPA and it improved performence
greatly but it's still far from what it should be.
glmark2 and glxgears run without problems. glmark2 reports in every
result more than 2 thousand fps while glxgears as expected about 60 fps.
Unfortunately in the Heaven 3.0 benchmark the performance is terrible
compared to Gnome Shell and E17 Ecomorph.

I'm also having problems with sound (Open Sound System v4.2-2006) while running
this Unigine benchmark (stuttering) and they only occur in Unity. The same goes
for games run through Wine but even native Trine 2.
I'm sorry that I don't provide results for Gnome Classic with Compiz but
it's because when I select it in LightDM the thing that shows up is
Gnome panels and Unity Dock. I think it's not the way it supposed to be.
