Swift Performance

Swift Performance is a WordPress cache plugin with AI-driven speed optimization. It targets Core Web Vitals: Largest Contentful Paint, First Input Delay, Cumulative Layout Shift, First Contentful Paint, Interaction to Next Paint and Time to First Byte.

Preloading handles important images and fonts and delays less important resources to improve LCP. JavaScript parsing and execution are tuned for logged-in users and non-cacheable pages to lower First Input Delay. JavaScript, CSS and fonts are tuned for real users, not only testing tools, to cut layout shift. Critical CSS and intelligent preloading reduce First Contentful Paint on mobile devices with poor connections, and preloading and caching keep Time to First Byte low.

The plugin includes AI optimization, critical CSS and JS optimization, image optimization and WooCommerce support.
