3d to flash, too late?

Simply test it yourself

var a:Array = [new BitmapData (1, 1), new BitmapData (1, 1)];
            var v:Vector.<BitmapData> = new Vector.<BitmapData> (2, true);
            v [0] = a [0]; v [1] = a [1];

            var t0:int = getTimer (), i:int, bd:BitmapData;
            for (i = 0; i < 1e8; i++) bd = a [i % 2];
            trace (getTimer () - t0); // 10204

            t0 = getTimer ();
            for (i = 0; i < 1e8; i++) bd = v [i % 2];
            trace (getTimer () - t0); // 10078

will now re-test in release mode

edit: release mode test

var tf:TextField = new TextField; tf.autoSize = "left";
            var s:String = "";
            
            var a:Array = [new BitmapData (1, 1), new BitmapData (1, 1)];
            var v:Vector.<BitmapData> = new Vector.<BitmapData> (2, true);
            v [0] = a [0]; v [1] = a [1];

            var t0:int = getTimer (), i:int, bd:BitmapData;
            for (i = 0; i < 1e8; i++) bd = a [i % 2];
            s += (getTimer () - t0) + " ";

            t0 = getTimer ();
            for (i = 0; i < 1e8; i++) bd = v [i % 2];
            s += (getTimer () - t0);

            tf.text = s; addChild (tf);

10281 10188

so, I'm back to what I said: I would sure like to see some test code, please.

edit: ok, I'm also getting results like 10296 10360 but that's ~3% fluctuation, at least both methods perform equally fast/slow, without clear winner any way. except with Vectors you get compile-time type checking and code hints, which is clear winner in my book
