How to Reduce CMS Page Load Time
IntermediateQuick Answer
TL;DR
Measure first with Lighthouse or WebPageTest, then address the highest-impact issues: optimize images, enable gzip/Brotli compression, deploy a CDN, minimize render-blocking JavaScript and CSS, implement caching headers, and switch to SSG or edge rendering to reduce Time to First Byte (TTFB). Most CMS sites can cut load time by 50-70% by fixing images and rendering strategy alone.
Key Takeaways
- Always measure before optimizing — Lighthouse identifies your specific bottlenecks
- Images and JavaScript are the two largest contributors to slow CMS page loads
- Switching from server-side rendering to SSG or ISR is the fastest way to reduce TTFB
- Compression, caching headers, and CDN delivery compound all other optimizations
