Performance Test

This will continuously add tweens until Tween is taking over 15ms per tick (ie. slightly better than 60fps). Note that this only accounts for the time spent in Tween; some browsers have additional overhead that could result in the actual framerate being noticeably lower than 60fps. Safari amy also throttle the test to 30fps, which makes getting accurate results difficult for that browser.

It will update the stage for the first 3 seconds (to confirm functionality), then stop rendering to isolate tween performance.
