I have spent quite a lot of time searching for the answer to this question and have not found a definite answer yet. I was hoping that either someone directly involved with creating Mir or someone very knowledgeable about it's inner workings would be able to help answer my question.
The situation: For some odd reason my laptop lags horribly with Unity 3D & 2D (I have tried all kinds of tweaks and stuff and nothing I have found works). I use Gnome 3 and have no problems whatsoever with lag, but I wish I could run Unity.
The question: I was wondering If Mir was going to use less system resources than the current incarnation of Unity. Should get my hopes up, or just resign myself to a lighter desktop on my laptop?
