Fix slow Next.js page loads by auditing your codebase to identify sequential data fetching waterfalls and large bundle sizes. Replace sequential fetches with parallel data loading using Promise.all or Suspense to significantly improve performance.

React performance optimization best practices include eliminating data waterfalls, reducing bundle size, optimizing server-side rendering, and improving JavaScript execution efficiency using a curated checklist of 57 rules.

Run a React performance audit using automated checking scripts to identify bottlenecks like unnecessary re-renders and sequential data fetching. This process highlights critical issues and provides a prioritized checklist for code reviews.

Yes, this optimization approach works with both React and Next.js, providing specific rules for optimizing server-side and client-side rendering, eliminating waterfalls, and reducing bundle size across both frameworks.

Data fetching waterfalls occur in web development when requests are made sequentially rather than in parallel. Identify these bottlenecks during a code review and resolve them using Promise.all or Suspense for parallel fetching.
