Is there any performance difference among having 2 enterFrames over 1 object ‘N’; or having 1 enterFrame over the same object ‘N’.

ie:  
_//from objectA_  
main.addEventListener(Event.ENTER\_FRAME, onEnterA);  
funtion onEnterA(){  
//objectA actions  
}

_//from objectB_  
main.addEventListener(Event.ENTER\_FRAME, onEnterB);  
funtion onEnterB(){  
//objectB actions  
}

VS

//from main  
this.addEventListener(Event.ENTER\_FRAME, onEnterMain);  
funtion onEnterMain(){  
//objectA actions  
//objectB actions  
}
