Subject: [osflash] Help: test EventDispatcher speed please

 

Hello list !

 

I noticed something weird about EventDispatcher execution speed in my
mac player.

EventDispatcher.dispatchEvent execution is slow compared to a custom
dispatcher implementation (named EventBroadcaster).

 

On Mac, EventDispatcher is slow:

EventBroadcaster: 2925

EventDispatcher: 12438

 

On Pc, EventDispatcher is faster.

EventBroadcaster: 3908

EventDispatcher: 3407

 

Can you please report the values you got (displayed on screen) when you
open the url below and the browser you used for testing.

It takes few seconds to initialize (bench with iterations)

Any clue is welcome. ;)

Thanks in advance guys !

Content of the test:

 

var tf1 : TextField = new TextField();

var tf2 : TextField = new TextField();

var tf3 : TextField = new TextField();

tf2.y += 30;

tf3.y += 60;

tf1.width = tf2.width = tf3.width = 150;

this.addChild( tf1 );

this.addChild( tf2 );

this.addChild( tf3 );

                                    

var holder : Array = new Array();

var l1 : Number = 10000;

var l2 : Number = 10000;

var lNum : Number = 500;

            

var eb : EventBroadcaster = new EventBroadcaster ( this );

var ed : EventDispatcher = new EventDispatcher ();

                                    

while( --lNum -(-1) )

{

            var tg : Object = {foo:function( e : Event ):void{ this.e =
e.type; }};

            ed.addEventListener( "foo", tg.foo );

            eb.addEventListener( "foo", tg );

            holder.push( tg );

}

 

var t : Number = 0;

var e : Event = new Event( "foo" );

       

//

t = getTimer();

while( --l2 -(-1)) eb.broadcastEvent( e );

t = getTimer() - t;

trace( "EventBroadcaster: ", t );

tf1.text = "EventBroadcaster: " + t;

//

t = getTimer();

while( --l1 -(-1)) ed.dispatchEvent( e );

tf3.text = flash.system.Capabilities.version;
