How to optimize server-side rendering to improve page loading experience?

When looking to enhance the page loading experience, optimizing Server-Side Rendering (SSR) focuses on reducing rendering time and resource transfer costs, typically addressing three aspects: rendering efficiency, resource processing, and caching strategies. Optimize rendering logic: Streamline the server rendering process by reducing unnecessary database queries or API calls, using asynchronous processing for non-critical data (e.g., user behavior statistics), and prioritizing the rendering of core above-the-fold content. Optimize resource transfer: Enable Gzip or Brotli compression for HTML output, remove redundant code (such as unused CSS/JS), and distribute static resources via CDN to reduce network latency. Implement caching strategies: Apply page-level caching for frequently accessed static pages or semi-dynamic content (e.g., product detail pages), and use fragment caching for dynamic components (e.g., user information) to reduce repeated rendering. It is recommended to use performance monitoring tools (e.g., Lighthouse) to identify rendering bottlenecks, prioritize optimizing first-screen loading time and interaction latency, and gradually improve overall page response speed.
