To eliminate data fetching waterfalls in Next.js, parallelize data fetching across server components rather than awaiting sequential requests. This pattern cuts response times by executing requests concurrently and deferring awaits until all parallel fetches are initiated.

The best way to reduce React bundle size is avoiding barrel imports and instead using precise imports, dynamic imports, and conditional loading. This prevents unused code from inflating the bundle and delays loading non-critical UI components.

Suspense improves React performance by allowing conditional loading and deferred rendering of UI components. It enables faster initial paint by streaming HTML and showing fallback UI while slower data fetching or component rendering completes in the background.

Yes, you can use per-request caching to optimize server-side rendering in React. It minimizes serialization and deduplicates fetches during the render pass, ensuring efficient data fetching without redundant network calls within a single request lifecycle.

Apply memoization in client components when optimizing transition-based updates and deduplicating fetches. It prevents unnecessary re-renders by caching expensive computations and data, ensuring smoother user experiences during client-side state changes.
