React has never been about speed (if you look at the official dev posts, speed is never listed as a top priority) but rather about not being slow (sCU check and whatnot). It's the slowest vdom implementation I know of, but it's fast enough and the network effects from being the biggest make it good enough. If you're interested in faster vdoms then check out inferno (fast), snabbdom (simple), mithril (compact), or domvm (flexible).
