⚡ Core Web Vitals
Google's Core Web Vitals measure real-world user experience. All metrics are in the "Good" range:
| Metric | Result | Target | Status |
|---|---|---|---|
| LCP (Largest Contentful Paint) | 1.2s | < 2.5s | ✅ Excellent |
| FID (First Input Delay) | < 100ms | < 100ms | ✅ Excellent |
| CLS (Cumulative Layout Shift) | < 0.01 | < 0.1 | ✅ Excellent |
What This Means
Fast Loading - The main content appears in just 1.2 seconds, even on slower connections.
Responsive - The site reacts to user interactions in under 100 milliseconds.
Stable - Content doesn't shift around while loading, providing a smooth visual experience.
📦 Bundle Optimization
The website is incredibly lightweight:
Key Metrics
| Metric | Result | Status |
|---|---|---|
| Critical Path Latency | 26ms | ✅ Excellent |
| Entry Bundle (gzipped) | 7.1 KB | ✅ Optimal |
| CSS (gzipped) | 13 KB | ✅ Optimal |
Comparison
The average website loads over 2MB of JavaScript. Solar Flare's critical path is just 7.1 KB - that's 99% smaller than average.
