To improve performance in a Next.js application, you can implement several strategies. Firstly, leverage server-side rendering (SSR) to generate pages dynamically on each request, reducing the time to first byte (TTFB) and improving perceived performance. Next, use the getStaticProps and getServerSideProps functions to pre-render pages and fetch data at build time or request time, respectively, reducing the need for client-side rendering and improving loading times. Additionally, optimize images and assets by using formats like WebP, lazy loading, and minimizing the use of large libraries. Caching data and assets can also significantly improve performance by reducing the number of requests to the server.
