Performance issue when moves child component

Question

Hi
     I am using flex 3.5. When i moved a HBox(with 150 labels and textinputs), from container A to B, it takes lot of time. Any ideas Or tricks to improve the performance.
Thanks,

Hi Alex,
     After a long try on that big source code, i found something makes it bad app. There is a code like this.
    1.   canvas.addEventListener("updateComplete", UpdateCompleteHandler);
     private function UpdateCompleteHandler(event:Event):void
          (event.currentTarget as Canvas).height = ....
        2.
        override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void
               AddEventListener();
        here numchildren would be around 250 fields from 7 panels.
        private function AddEventListener():void
               for(var count:int = 0; count < this.numChildren; count ++)
                    (this.getChildAt(count) as compoent).setStyle('backgroundColor', 'red');
The above two scenorios eat CPU time alot. when i fixed them everything comes back good.
I don't say add child is working faster. but now it is good.
My question is how can i find which component eats CPU time alot? There is only 7 instance in this case. But they ate CPU time always.
Is there any ability to track CPU usage via profiler.
