My game is slow, any suggestions?

Hi, Im making a videogame like overbody else.
Is has turned well but, with more and more behaviors, actos, backgrounds imported to the game archive, it has become slow. The main problem appear when I finished to make proves with the actors, behaviors interactions in scene and when I began to construct de level, it becames to get slow. I already use recycle actors. Any suggestions so my game get running faster?

First, some of us discourage the use of recycled actors. They can be buggy/unpredictable, so to speak. :/

Second, check this out for some general performance help:

disable physics for some actors if you can.
