Comment 8 for bug 1240841

The first step should probably be to land all the optimizations we have in progress. What remains is bug 1227739, which still requires platform-api work.

I've only just got my own "manta" so will look to see if there are any obvious performance problems in Mir holding it back. One such issue I can think of is that our Android "fence" support is not yet complete. I don't really understand that stuff but know it's on kdub's list of things to do.
