var lii:URLLoader = new URLLoader();

addEventListener(Event.ENTER_FRAME,init);

stage.addEventListener(Event.RENDER,render);

var url:String  = "http://flashdn-nctalk.ktics.co.kr/BnS_20091127/BNS_FullMovie_download.zip";

var aone:Sprite = new Sprite();

aone.graphics.beginFill(0xFF0000);

aone.graphics.drawRect(0,0,100,100);

aone.graphics.endFill();

aone.x = aone.y = 100;

addChild(aone);

function init(e:Event):void {

        lii.load(new URLRequest(url));

        stage.frameRate = 0.0000001;

        removeEventListener(Event.ENTER_FRAME,init);

}

function test(e:ProgressEvent):void {

        aone.x +=.1;

        aone.rotation += 1;

        stage.invalidate();

        stage.quality = StageQuality.HIGH;

}

function render(e:Event):void {

        trace("render");

        //不会触发render事件的渲染

}

 

trace(1 / 0.0000001 / 60 / 60,"小时/帧") //2777.777777777778 小时/帧
