Why Static Websites Are Faster Than Most WordPress Sites

Speed is a critical factor for both user conversion and search engine ranking. When a browser requests a WordPress page, the server has to run database queries to assemble the content dynamically, parse PHP scripts, and download heavily nested asset files before rendering. This database handshake creates a bottleneck known as Time to First Byte (TTFB).

The Pre-Compiled Architecture

Static site generators like Astro pre-compile the entire page structure during build time. The server does not have to assemble anything on the fly. When a user visits the URL, the edge server simply sends the raw HTML. This edge delivery yields TTFB speeds of under 50ms, compared to the 300ms to 800ms typically seen on database CMS architectures.

Lighthouse Dominance

By eliminating server-side compile bottlenecks and removing unused CSS/JS scripts, static site builds consistently score perfect 100s in Lighthouse and Core Web Vitals audits.
