Eliminate data fetching waterfalls in Next.js by parallelizing data requests and applying Suspense boundaries to prevent long chains of waiting. Batch independent fetches together instead of requesting them sequentially to deliver faster user experiences.

Use React Server Components to maximize efficiency across server environments, and establish client boundaries only when necessary. Apply server and client patterns with caching strategies like React.cache or SWR to optimize rendering performance across contexts.

Reduce initial bundle size in a React application by using dynamic imports, code-splitting, and selective imports. Apply memoization to prevent unnecessary re-renders and use dynamic imports specifically for heavy components to optimize loading performance.

Yes, you can use SWR for data deduplication alongside React Server Components. Combine SWR caching strategies with server and client boundary patterns to maximize efficiency and enforce consistent data-fetching logic across both environments.

React components re-render unnecessarily during data updates when memoization is absent. Apply memoized components and use SWR for data deduplication to prevent redundant renders, ensuring efficient state updates and faster UI responsiveness.
