React + Redux: Performance & Scalability
summary
Shows that normalizing the Redux store and using reselect’s memoized, composable selectors greatly improves performance and scalability. Measured on a calendar app, this approach reduced scripting time by ~20–27% and render time by ~94.1% in incremental updates (other tests showed ~50% scripting and >60% rendering gains). Recommends creating per-instance selector factories in mapStateToProps to avoid cache misses, keeping derived-data generation inside selectors (not components), and using tools like normalizr, reselect, and Redux Toolkit.
