To optimize React and Next.js performance and remove data fetching waterfalls, you must parallelize async work and apply React.cache or LRU patterns. This restructures sequential server-side fetches into parallel streams, significantly reducing load times.

The best way to reduce bundle size and client rerenders in Next.js server components is using dynamic and conditional imports. This minimizes RSC serialization overhead and ensures components only load when required, shrinking the initial payload.

Suspense streaming improves Next.js hydration by sending HTML chunks progressively rather than blocking the entire page. This mechanism allows the client to hydrate available components immediately while waiting for slower asynchronous data to resolve.

Yes, you can apply these React performance rules to refactor API routes and client data fetching. The optimization guidance covers RSC boundaries and API routes, helping minimize serialization overhead and unnecessary client rerenders across workflows.

Your Next.js app ships large client bundles due to inefficient imports and suboptimal data-fetching patterns. You can restructure components by applying prioritized optimization rules like dynamic imports and Suspense streaming to enable parallel streaming.
