I don't particularly see a performance issue as far as TM slowing down or something of the sort when this happens, I really only noticed this because any new file I'd open wouldnt have syntax highlighting, and fans would go crazy after a little while on this. At first wasn't sure what was causing this, then I figured out that opening any minified js file or a long js file would cause this. Instantly highlighting stops for all other files and TM process goes over 100%. Only way to stop is force quitting.

Same here, other than that TM2 has been quite pleasant to work on.
