I agree with Michael - great test! If you could add a scale, a 95% confidence interval and automate the tests (e.g. using python, AppleScript, …) it would be fantastic.
In my local tests I recognized that the times vary a lot at the beginning.

Hey, great test, very interesting results. Just a small note, it would be helpful to add in a scale on the vertical axis of al your graphs - so we know whether the graph is measuring in ms or fathoms. Or even just mention that ’smaller is better’ somewhere would be a help. HTH ;)

Would be very interesting how the current WebKit fits into this picture. See http://trac.webkit.org/changeset/34618

Hey Dave, thanks for commenting, good to know it’s something you guys are aware of and working on.

Your tests actually just exposed an O(n^2) parsing bug with the style element in WebKit. I am working on fixing the bug, but I thought you should know that the reason you are getting odd results in WebKit has to do with that bug (and not with selector matching).
