Advanced performance optimization for WordPress
Hummingbird Pro is the paid edition of Hummingbird Performance, a WordPress plugin for improving page speed and addressing recommendations from Google PageSpeed Insights. It combines caching, asset optimization, compression, resource prioritization, and performance guidance in one toolkit.
The Pro edition is available through the WPMU DEV Membership and adds advanced controls for sites that need more than the free plugin’s one-click optimization features. It is suited to site owners and WordPress professionals who want a more structured way to scan, refine, and monitor website performance.
Pro performance features
Hummingbird Pro includes automated scanning to help identify performance issues, along with uptime monitoring. Enhanced minify compression provides two times the regular optimization described for the free version, while CDN-hosted minification helps deliver optimized assets through the content delivery network.
Pro also includes Delay JavaScript Execution, which postpones non-critical JavaScript files and scripts until user interaction. This can help address JavaScript execution time and reduce the effect of non-essential scripts during the initial page load.
Critical CSS Generation automatically prioritizes above-the-fold styles. Hummingbird Pro also includes Brotli file compression through the CDN and access to a 119-point global asset CDN with unlimited bandwidth, according to the supplied product information.
Core tools for a complete workflow
The plugin provides a full caching suite with full-page, Gravatar, and browser cache tools. Asset Optimization can combine, compress, and position JavaScript, CSS, and Google Font files. Additional controls include CSS and JavaScript minification, preloading key requests, preconnecting to required origins, deferring unused CSS, and moving critical CSS and JavaScript inline while deferring non-critical resources.
Lazy Load integration can defer offscreen images, with the supplied information also describing integration with the free Smush plugin. Hummingbird can work with Cloudflare’s APO and browser cache. For WooCommerce, the cache settings should follow WooCommerce recommendations; cart, account, and checkout pages are excluded to keep their content dynamic.
Safer testing and practical use
Safe Mode lets logged-in administrators test Hummingbird settings without changing the optimized experience seen by visitors. This is useful when adjusting asset movement, combination, minification, or defer settings, since those changes can affect styling and functionality.
Use Hummingbird Pro when you want to review site performance, apply compression and caching improvements, optimize the delivery of CSS and JavaScript, and monitor the results over time. Performance reports provide guidance for running the site at higher speed.
Installation and setup
Install Hummingbird in WordPress and connect the site through the WPMU DEV Membership to access the Pro features described above. Run a scan, review the recommendations, and apply changes incrementally. Test key pages after each adjustment, especially when changing Asset Optimization, JavaScript execution, or cache settings.
