I'd agree that MobX generally gives you good performance out of the box, but I'd definitely disagree that Redux's performance situation is a "nightmare".

One of the keys to good Redux performance is to connect more components, and have each component only extract a small piece of the state [0]. Using memoized selector functions also helps in most situations [1].

FWIW, there was a really good discussion on the relative strengths and weaknesses of Redux and MobX in regards to performance a while back [2].

I really like that mobx + vuex have their version of "memoized selectors" (computed getters) straight out of the box, fully integrated. They're so insanely useful.
