Hello

I need to create many spark.components.Group objects (more than 10000) and have some performance problem. In many cases new object was created in 0-5 ms, but sometimes in 266-700 ms.

This is output from my test app (code below):

[Time] - [Count]

0 - 91035
1 - 7308
2 - 393

3 - 365

4 - 408
5 - 404
6 - 66

7 - 3

8 - 3
9 - 2
10 - 1

12 - 1

13 - 1

16 - 1

19 - 1

24 - 1

39 - 1

63 - 1

67 - 1

210 - 1

260 - 1

266 - 1

690 - 1

And code:

            var map:Object = new Object();
            var i:int, start:int, stop:int;
            var grp:Group;
            for(i = 0; i != 100000; i++) {
                start = new Date().getTime();
                grp = new Group();
                stop = new Date().getTime();
                if (!map.hasOwnProperty(stop - start)) {
                    map[stop - start] = 0;
                }
                map[stop - start]++;
                container.push(grp);
            }
 
            for (var key:* in map) {
                trace(key + " - " + map[key]);
            }
    }
 
    ]]>
    </fx:Script>
</s:Application>

Can you test this code in yours computers?

Anybody know where is a problem? I don't have any applications run in background. etc...
