To fix React and Next.js performance issues, apply actionable rules that parallelize async work, minimize RSC serialization, and implement targeted bundle optimizations to prevent waterfalls and shrink bundle size.

The best way to optimize React Server Components boundaries is by minimizing RSC serialization and applying correct caching strategies during component refactoring to reduce unnecessary data transfer and slow rendering.

Prevent unnecessary re-renders with SWR by applying targeted rendering optimizations and correct caching strategies during client data fetching, ensuring efficient data flows that improve TTI and LCP metrics.

Yes, you can use Vercel-style performance rules to review existing Next.js codebases by checking changes for performance regressions and applying incorrect versus correct rule patterns to refactor components and pages.

Slow rendering and large bundle sizes in Next.js applications are often caused by common architectural inefficiencies, which you can resolve by parallelizing async work and applying targeted render and bundle optimizations.

You should carefully evaluate RSC usage when client fetching with SWR is more appropriate, ensuring you minimize RSC serialization overhead and apply correct caching strategies to avoid architectural inefficiencies.
