Optimizing Next.js Performance for Scale

Performance is user experience. A slow site is a broken site. With Next.js 15+, we have an incredible toolkit for building lightning-fast applications, but only if we use it correctly.

Server Components First

By moving logic to the server, we reduce the client-side bundle size and improve First Contentful Paint. It's a paradigm shift, but one that yields massive dividends for performance.

Image Optimization

Images are often the heaviest assets on a page. Using the Next.js Image component with proper sizing and formats like WebP or AVIF is non-negotiable for a modern web app.

Edge Caching

Why serve a user in Tokyo from a server in Virginia? Edge middleware allows us to deliver content from the node closest to the user, drastically reducing latency.
