To fix React and Next.js performance regressions, standardize best practices to detect and resolve data fetching waterfalls by applying parallel data fetching patterns and Suspense boundaries. This reduces rendering bottlenecks and improves loading metrics.

The best way to reduce bundle size in a Next.js application is to apply bundle optimization patterns across client and server boundaries, utilizing dynamic imports to defer non-critical work and minimize the initial JavaScript payload.

Optimize server and client boundaries during Next.js component refactoring by applying actionable patterns that correctly segregate server actions and client-side logic, ensuring data fetching remains efficient and bundle sizes stay minimal.

Use Suspense boundaries in React and Next.js projects when you need to defer non-critical work and eliminate data fetching waterfalls. Implementing them as a top-priority pattern helps systematically resolve performance inefficiencies.

Audit a Next.js page for performance bottlenecks by reviewing components, pages, and data-fetching logic to identify inefficiencies. Apply recommended patterns like Suspense boundaries and bundle optimizations, then verify TTI and LCP metric improvements.
