I usually come away from things like this with the distinct impression that they're pretty much all "fast enough" for my needs. Admittedly, I'm not asking a lot of JavaScript, and my skill level with JavaScript tends to lead me to take the path of least resistance, or at least the path of best documentation and most examples.

That said, this kind of third-party benchmarking is probably useful, because so many frameworks have benchmark charts on their own site which indicate they're all faster than everything else. (Which may not even be inaccurate...for the things they benchmark, they may be the fastest. Which again maybe indicates they're all "fast enough" and unless your use case exactly matches that of the specific benchmarks in question, the benchmarks might be misleading you about which one will be fastest for your app.)

Also, I had no idea there were so many JavaScript frameworks that I hadn't heard of (and there's at least a few that I have heard of that aren't on the chart). Every time I turn around, there's two or three more JavaScript frameworks. Surely, this will calm down at some point, and a couple of leaders will emerge and folks will kinda settle into moving those leaders forward rather than reinventing everything?
