- Static shell prerendering coupled with dynamic React 19 Suspense streams achieves instant sub-50ms First Contentful Paint.
- Cache components with granular tags enable instant invalidation without full page re-renders.
- Native Turbopack compilation runs hot module reloading in under 12ms even on 10,000-module monorepos.
Series: Modern Web Runtimes (Part 3 of 5)
