Out of curiosity, why do you say "don't care much about performance"? Redux can be _extremely_ performant, although it does take a bit of thinking about how your data is organized. I've got several articles discussing Redux performance [0] in my React/Redux links list [1]. In particular, check out Dan Abramov's PR to a MobX/Redux benchmark [2], and the article "High Performance Redux" [3]. Finally, the upcoming React-Redux v5 release shows noticeable improvements in a variety of scenarios [4].
Any specific issues with Redux performance that you've noticed?
