Hello.  
I’m developing a game right now and after I did a lot of coding I started to notice some lag.  
I have only one onEnterFrame = function() in the main timeline but about 30 onClipEvent(enterFrame) that run simultaneous and I think that this is the problem.

I was wandering if replacing onClipEvent(enterFrame) with function called from the main onEnterFrame could help a bit.

Moving the codes from onClipEvent to the main timeline is not a very good option since it’s very hard to do but if there is no other solution and if this may improve performance I shall do it.

Please help me with a suggestion. If you know any means of improving performance I want to hear them.
