I'm not sure about that. I'll follow up with some of my colleagues to see why typed arrays are in such an state.
Am I correct in assuming that if JavaScriptCore starts successfully executing the tests, it'll automatically start showing up on the relevant part of arewefastyet.com?
I am not sure about automatically showing up, but that would be my guess. I can ask dvander (who runs awfy) for more details if that would be useful. In any case probably it is very easy to change (disable/enable).
