I don't think performance issues with 10966 are specific to Mac OS X. I upgraded to 10966 on my Ubuntu 14.04 setup and it was so bad as to be unusable. In order to do any mapping again I had to downgrade to 10786 (fortunately only one plugin requires the latest version, and it's one I don't need right now).

The symptoms in my case were continuous swapping out, basically JOSM would just eat as much memory as the system would give it to the point of using up all my ~6 GiB of swap space (I am on a laptop with only 2 GiB RAM).

Probably fixed by now. If you experience again performance problems, please try to disable all plugins, update Java, and if the problem persists, create a new ticket by attaching a complete step-by-step scenario and if possible a thread/memory dump. These kind of issues can be tricky to resolve without dumps.
