How can you improve performance in a Next.js application?

To enhance performance in a Next.js application, developers can implement a combination of rendering strategies and optimization techniques. One of the most effective approaches is using Server-Side Rendering (SSR) to dynamically generate pages per request, reducing the TTFB and improving perceived load speed.

Additionally, take advantage of getStaticProps and getServerSideProps to pre-render pages during the build or request time. This minimizes client-side data fetching and improves initial load times. Incorporating automatic image optimization—with lazy loading and modern formats like WebP—also helps reduce payload sizes.

Further enhancements include caching data and assets to limit server requests and reducing the use of large, unnecessary libraries. These strategies together ensure a faster, more scalable, and user-friendly Next.js application.
