I think the difference is very big. It seems AS VM optimization is too bad in
the body of a for loop. Here is another test, more simple.
static function test(text:TextArea):void{
var loop:int = 0;
var i:int = 0;
var j:int = 0;
var k:int = 0;
var now:Date = new Date();
var d:int = 1;
for(i=0;i<10;i++){
for(j=0;j<10000000;j++){
d=1; //Comment out this to see
difference
}
now = new Date();
text.text+=(""+now.getTime()+"
"+d+"\n");
}
}
If d=1 is executed it cost 10seconds ,if it not execuetd it cost 1 seconds. Can
you try to repeat it on your machine,may be I use some wrong complier options.
