Could not sign-in/create account to the blog comment thingy, so asking here:

Is there performance numbers available per browser in Android somewhere and to which browser the mentioned numbers apply?

Traditionally the vendor shipped browsers in Android are abysmal, out of date, probably insecure and not standards compliant. So what I am really interested about is stock Google Chrome or Firefox performance. And if these numbers are from either one of those, it would be nice to know.
