Super Page Cache Pro
Cache pages on disk and at Cloudflare's edge, then defer and delay JavaScript for faster loads.
About This Plugin
Super Page Cache Pro speeds up WordPress with full page caching on your server's disk and on Cloudflare's CDN, which works on Cloudflare's free plan. The cache clears the moment you update content, and tag-based purging clears only the pages a change affects, with REST and WP-CLI tools.
Pro removes render-blocking scripts. Defer JavaScript improves initial load times, and Delay JavaScript waits to load scripts until a visitor scrolls or clicks. Smart lazy loading detects above-the-fold images and loads them right away while the rest load on scroll, for better LCP scores.
It also lazy loads videos, iframes and backgrounds, caches around nonces so forms, carts and AJAX keep working, and cleans spam comments and old revisions out of the database.
