React Native Performance Issues and Optimization Techniques

This page contains a table that provides an overview of common performance issues encountered in the development process and suggests optimization techniques to address them It also includes detailed performance reports for each optimization problem discussed in the table. Lastly, the page includes activity diagrams for each of the performance optimization techniques. These diagrams visually depict the flow of activities involved in testing and applying the optimization techniques.

Performance Reports For:

Performance issues and ways to address them
Performance Issue Optimization Technique
Unnecessary Re-renders/Inefficient Rendering Memoization
Using useReducer() instead of useState()
Fragments
Using useEffect() dependencies efficiently
Slow App Startup Time Code splitting
Tree shaking
Lazy loading
Threads Bottleneck Removing Logs
RenderToHardwareTextureAndroid
InteractionManager
useNativeDriver in Animated
Slow Render of Lists Selecting appropriate List type
Parameters tuning
Performance Reports For:
Re-render / Inefficient Rendering Performance Reports
  1. How console logs impact performance
  2. HardwareTexture - Animations
  3. HardwareTexture - Heavy Rendering
  4. HardwareTexture - Lists
  5. InteractionManager

    This is short gif comparing the Time To Initial Render of two components. One using the interactionManager and one without it

  6. NativeDriver
