(Get the code!)
OK, So I've finally been able to do a bit of testing with Ubuntu 14.04
If run without 3d support on llvmpipe, it's very CPU-hungry. A bit more so than Ubuntu 13.04 AFAICT. For Ubuntu on VMware this becomes troublesome primarily on ESX, but the problems were introduced with the drop of Unity 2D. I haven't dug thoroughly into why it hurts so much on ESX. Could it perhaps be that Unity / Compiz is performing full-screen flips when only a part of the screen is updated?
Also we have severe performance problems when running fully 3D accelerated with workstation / fusion on multi-monitor setups. That's partly due to how the VMware device updates screens but Ubunut 14.04 stands out as particularly slow here. Also needs further investigation...
