Status: RESOLVED DUPLICATE of bug 497788

(Core :: General, defect)

Description

[Jeff Muizelaar [:jrmuizel]]

Chrome runs at about 200 fps. Safari at about 98 fps, and us at 86fps. Not sure why yet.

Chrome doesn't self-limit timeouts to 10ms minimum delay. Other browsers do.

We spend about 20% in js: getting and setting. About 40% in painting and the rest scattered about.

Yes, that looks like the reason.

However, if you set the number of balls to 128 and adjust the setInterval time to 10ms Chrome gets 72fps and we get 25fps. So there's still some work we can do here.

Yes, there's more to do, but this is already tracked at bug 497788.
