I’m working on a large-scale React application with Redux for state management, and I’m encountering performance issues during rendering. The application has multiple complex components, and as the data grows, the rendering time becomes noticeable, especially on initial load and when navigating between routes.

I’ve already optimized my components using shouldComponentUpdate, PureComponent, and React.memo where appropriate, but I’m still experiencing sluggish performance.

I suspect that the performance bottleneck might be related to how Redux manages state updates and how the components are connected to the Redux store. I’m using mapStateToProps and mapDispatchToProps extensively throughout the application.

Could someone provide guidance on advanced performance optimization techniques specifically for React applications using Redux? Additionally, how can I better trace and diagnose performance bottlenecks in my application?

I’m open to suggestions, best practices, and tools that can help improve the rendering performance and overall user experience. Thanks in advance for any help!”
