I get that, the Kangax table was just an example I literally ran into moments before. But for a more "pure" js example, I have an app which does some image processing in the browser using the canvas ImageData stuff and typed arrays. For whatever reason my test case completes in about 3 seconds in chrome, 3 to 4 seconds in FF, 11 seconds in IE11, and 6 seconds in Edge. I've profiled the hell out of it and i just can't figure out the reasoning for it, but it's there. (and as a side note, having the dev tools open in Edge obliterates javascript performance, my test case was taking 30+ seconds to run when i had the dev tools open and it took me longer than i'd like to admit to figure that one out) I have a feeling the problem is that i'm optimizing for V8 because i know it the best, and i'd much rather not do that if possible.
