🚀 What WP Fastest Cache Does
WP Fastest Cache works by generating static HTML files from your dynamic WordPress pages and serving those cached versions to visitors — which reduces the number of PHP and database calls needed on each visit, leading to faster page load times and lower server resource usage.

In addition to core caching, it includes several optimization tools that help speed up your site, both in its free and premium versions.
