[flexcoders] Help: test EventDispatcher speed please

[Francis Bourre]

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 !
