6 React Server Component performance pitfalls in Next.js

Developers often adopt React Server Components to enhance app performance, aiming for faster initial loads and reduced client-side JavaScript through server-side data fetching and UI streaming. However, production realities reveal common pitfalls that can hinder these benefits, such as blocking UI rendering with slow data requests, inefficiently handling large data transfers between server and client, and excessive client-side hydration. These issues result from misplaced async boundaries and can make applications feel sluggish, despite fast backend operations. To address these challenges, developers should strategically manage data fetching, utilize Suspense for non-critical data, and refine client-server boundaries to ensure UI responsiveness. By focusing on these aspects, applications can maintain a modern, responsive feel without requiring extensive rewrites.
