ReactJs Performance ~ Server-Side Rendering (SSR) and Static Generation ~

Short summary

SSR and SSG shift rendering from client to server, reducing load times from 2-4s to 0.5-1.5s and 0.2-0.8s respectively. Post includes Next.js code examples, performance comparison tables across rendering strategies, and a four-phase implementation roadmap for rolling out 15 optimizations.

• •SSR pre-renders HTML server-side, cutting load time to 0.5-1.5s vs 2-4s for CSR
• •SSG with CDN achieves fastest loads (0.2-0.8s); ISR adds dynamic updates to static speed
• •Concrete Next.js examples and phased roadmap (weeks 1-12) for adopting optimizations
