P.P.S. - We found a subtanstial improvement for OSX performance that was a small change so we decided that should go into 0.92.2. Also should have minimal impact (simply disabling AppNap, I think).
App Nap has been disabled for people running OS X 10.9+. This will result in much-improved performance. In addition, there is a Qt patch I created that I'm
in the process of trying to get approved/modified. This patch is needed to prevent some crashes that were still occurring in 0.92.1. I'm still troubleshooting some minor OS X bugs but at least I haven't seen any more crashes since creating the Qt patch.
