About This Plugin
Hummingbird Pro is a WordPress speed plugin covering file compression, minification and caching. It works with all major hosting platforms.
Asset Optimization minifies and combines CSS and JavaScript. Caching covers full page, Gravatar, RSS and browser caching, with control over Cloudflare caching and APO. Other tools include prefetch and preconnect, lazy load comments, font preloading, WooCommerce support and multisite support. A setup wizard gets you started.
Pro adds Delay JavaScript Execution, which loads non-critical JavaScript only after user interaction, and Generate Critical CSS for visible content. White Label support lets you customize the plugin for your clients. Automated database cleanup and average page speed tracking are in the free plan.
