Hi, I'm a Redux maintainer. I'll repeat the comment I made on your blog for visibility.<p>Running your reducers is almost never the perf bottleneck - updating the UI is. Most slice reducers are either switch statements or lookup tables, in which case there's effectively no work to do if the action doesn't matter for this reducer. See our FAQ entry at [0] for more details.<p>If you have specific examples where Redux performance is an issue, please ping me @acemarke in Twitter or Reactiflux, and I'd be happy to offer advice.<p>[0] Performance: Won't calling "all my reducers" for each action be slow? <a href="https://redux.js.org/faq/performance#wont-calling-all-my-reducers-for-each-action-be-slow" rel="nofollow">https://redux.js.org/faq/performance#wont-calling-all-my-red...</a>
