Fast fast fast! think!

I need toknow ways to make flash think… at least, in a more efficient way.

Like… Wath is more fast to flash? attaching a function multiples mcs like this: theMc.onEnterFrame=theFunction… or put all the mcs._names in an array and go from there… HELP!!!

Another thing, making objects is the same that making instans of a class??

And… making this. Class.prototype.stuff=? and making this. OBJ.stuff for every object… is the same? what is more efficient? If the object is the same but diferent in his variables. OK.
