https://www.w3.org/Bugs/Public/show_bug.cgi?id=24115 --- Comment #6 from Simon Pieters <simonp@opera.com> --- http://dev.w3.org/csswg/selectors4/#profiles I think a slightly more realistic benchmark doesn't use the same string every time, and also the proposal here would mean that jQuery would invoke both CSS.isValidSelector and then query(), which seems equivalent to calling querySelector twice, so: http://software.hixie.ch/utilities/js/live-dom-viewer/saved/2699 The throwing path is still a lot slower in Gecko and Blink, but in Presto the throwing code path isn't that slow. About the same as non-throwing in Blink and about twice as slow as non-throwing in Gecko. -- You are receiving this mail because: You are the QA Contact for the bug.
