Another thing, you need to use autodisable. It unregisters things that haven't moved for a certain amount of time. That way, the engine is not making unneeded calculations. You could re-enable them when the player is very close, or at any other time you need. Even though you don't realize it, physics objects sitting still are still performing tons of collisions per second. So disable the ones not in use to boost performance.
