Optimization Matrix
19 automated optimizations working together to deliver exceptional performance.
| Optimization | Category | Impact | Improvement |
|---|---|---|---|
Service Worker with Smart Caching Registers a Service Worker that implements intelligent caching strategies with automatic WebP transcoding for images. | Caching | High | 70 to 90 percent cache hit rate |
Strategic Resource Hints Injects preconnect and dns-prefetch hints for critical third-party origins like Google Fonts. | Network | Medium | 100 to 300 milliseconds faster font loading |
Native Lazy Loading with Fallback Applies native lazy loading to images with IntersectionObserver fallback for older browsers. | Images | High | 40 to 60 percent initial payload reduction |
Low-Resolution Placeholders Generates tiny 64x64px placeholders for large images, loading full resolution on-demand with WebP conversion. | Images | High | 95 percent smaller initial image payload |
Inline Small CSS Inlines same-origin stylesheets under 5KB to eliminate render-blocking requests. | CSS | Medium | 200 to 500 milliseconds render time |
Inline Tiny Scripts Inlines same-origin JavaScript files under 2KB to reduce HTTP overhead. | Scripts | Low | 1 to 3 fewer HTTP requests |
CDN Asset Rewriting Rewrites same-origin asset URLs to CDN when configured via meta tag. | Network | High | 30 to 50 percent faster asset delivery |
Safe Persistent HTML Modifications Injects or updates canonical links and JSON-LD structured data when explicitly enabled. | Network | Low | SEO and structured data improvements |
Third-Party Request Blocking Monkey-patches window.fetch to block requests to specified third-party domains. | Scripts | Medium | 100 to 500 milliseconds faster page load |
Background Optimization Trigger Sends messages to Service Worker to trigger background image warming and cache population. | Caching | Low | Proactive cache warming |
Runtime Feature Toggles Provides public API for enabling/disabling features at runtime via localStorage and SW messages. | Monitoring | Low | Dynamic optimization control |
Real Time Web Vitals Tracking Tracks FCP, LCP, CLS, and TBT using PerformanceObserver API with zero performance impact. | Monitoring | High | Zero overhead monitoring |
Automatic Image Dimensions Automatically sets width/height attributes and aspect-ratio CSS for images to prevent layout shifts. | Images | High | 0.1 to 0.25 CLS reduction |
LCP Image Promotion Identifies likely LCP candidate (largest above-fold image) and promotes with fetchpriority="high" and preload. | Images | High | 20 to 30 percent faster LCP |
Script Execution Optimization Automatically defers same-origin scripts and makes third-party scripts async to reduce blocking time. | Scripts | High | 30 to 50 percent TBT reduction |
Analytics Script Deferral Blocks analytics and tracking scripts until user interaction (click, scroll, touch, or 5s timeout). | Scripts | Medium | 100-300ms faster FCP |
Font Loading Optimization Preconnects to font CDNs, defers font stylesheets via preload, and injects font-display:swap CSS. | Fonts | Medium | 100-300ms faster text rendering |
Navigation Prefetching Prefetches up to 3 same-origin navigation links from nav/menu/header elements. | Network | Low | Instant navigation for prefetched pages |
WordPress Emoji Script Removal Removes unnecessary WordPress emoji polyfill script to reduce HTTP overhead. | Scripts | Low | 1 fewer HTTP request |
