Standard CMS vs. SparkDev Architecture
Real-world load speed and Core Web Vitals benchmark comparison.
Heavy plugins & uncompressed stylesheets
- Multiple blocking CSS/JS bundles delaying initial page render.
- Unoptimized images causing high Cumulative Layout Shift (CLS).
- Average server response time over 3.5 seconds on mobile.
Static generation with edge hydration
- Automatic route splitting & minimal JavaScript payload size.
- Zero layout shifts with Next.js explicit image dimensioning.
- Edge CDN distribution ensuring sub-second response globally.
