Definitely slower on a Mac
FF :
EventBroadcaster: 5021
EventDispatcher: 16148
Safari :
EventBroadcaster: 5845
EventDispatcher: 17080
Opera 8.5:
EventBroadcaster: 5469
EventDispatcher: 17635
Player MAC, 9,0,28,0
no clue as to why tho ...
Good luck !

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 !
