WP Speed of Light Pro Addon

This add-on extends WP Speed of Light, a WordPress speed-up plugin. It adds cache preloading, font optimization, DNS prefetching and automatic database cleanup at a defined frequency.

Cache preloading generates a first version of the page cache automatically, so the first visitor after a cache cleanup does not wait for it. DNS prefetching preloads DNS information for the external domains your links point to, so those pages load faster when a visitor clicks.

The base plugin adds a static page cache, GZIP compression, browser caching, HTML, CSS and JS minification, a separate cache per device, progressive image lazy loading and CDN integration with Cloudflare, Amazon CloudFront, MaxCDN and KeyCDN. It also includes Google speed tests, a database speed test and a dashboard that checks major performance issues.
