How to Reduce Round Trip Time (RTT) with Next.js

Round Trip Time (RTT) is the delay between sending a request to a server and receiving a response, which can significantly slow website loading as pages typically require 20-30 network requests. Next.js reduces RTT through Server-Side Rendering that delivers complete pages in one trip, React Server Components that render parts on the server, automatic image optimization, and static caching. These techniques minimize network requests and improve loading speeds, especially for users far from servers or on slower connections.
