To fix slow initial load times in Next.js, you can parallelize sequential data fetching to eliminate waterfalls and implement dynamic imports for heavy components to reduce your JavaScript bundle size.

The best way to audit React rendering performance is to evaluate your application against a prioritized set of rules covering asynchronous operations, bundle size, and re-render optimization to identify critical bottlenecks.

To optimize client-side data fetching in React and prevent waterfalls, apply targeted rules that eliminate sequential fetching patterns and restructure your asynchronous operations for parallel execution.

Yes, you can use these web vitals optimization rules for both React and Next.js projects, as they comprehensively cover server-side performance, client-side data fetching, and JavaScript micro-optimizations.

Your Next.js site might experience slow interactivity due to unoptimized server-side rendering or excessive component re-renders, which require targeted rendering performance rules and micro-optimizations to resolve.
