Performance was never the point of React. The point is to be able to (from a developer's point of view) re-render "everything", with every change, top down, without having to worry about the details. Doing that normally would be horribly slow, so React makes it adequately fast. So it's not "super mega high speed lib". It's "Gives you the ability to have a function which, given argument, renders an entire app, and can be called over and over and over" at pragmatic speed, allowing for easier code to reason about. If your primary goal is performance above all else, it's actually not that great a library.
