Super Page Cache Pro is a performance-focused WordPress plugin that dramatically speeds up websites by combining disk-level HTML caching with edge caching via Cloudflare – even on free Cloudflare plans. It supports intelligent features like lazy-loading for images/videos/iframes, deferred and delayed jаvascript execution, and script exclusions for tailored optimization.
