Optimizing React Native: 16 Performance Issues You’re Probably Facing
Article Summary
Most React Native performance problems aren't framework issues. They're developer knowledge gaps that compound over time.
Jamon Holmgren breaks down 16 common performance culprits he sees when clients complain about React Native apps running slow. The list reveals that most issues stem from basic React principles and lack of measurement, not the framework itself.
Key Takeaways
- Massive unnecessary rerenders from ignoring basic React principles top the list
- Missing basic config like cache and inline requires kills performance
- Loading spinners for short waits actually increase perceived slowness
- Heavy native modules loading at app start slow down launch times
- Waiting for all API requests before rendering creates unnecessary delays
Critical Insight
React Native performance depends on developer knowledge and measurement practices, not native versus cross-platform debates.
