 ## 🔥 React Server Components
 
-Server Components execute on the server and stream HTML to the client—no extra JavaScript in your bundle. Real‑world results include:
-
-- **62% reduction** in client‑side bundle size on productonboarding.com when migrating to RSC [[1]]
-- **63% improvement** in Google Speed Index on the RSC version of the same site [[1]]
-- **52% smaller** JavaScript codebase and Lighthouse scores rising from \~50 to 90+ on GeekyAnts.com [[2]]

 ## 🌊 SSR Streaming
 
 SSR Streaming sends HTML to the browser in chunks as it’s generated, enabling progressive rendering:
 
-- **30% faster** full‑page load times at Hulu by combining streaming SSR with Server Components [[3]]
-- Popular libraries like styled‑components v3.1.0 have introduced streaming SSR support as the next generation of React app rendering [[4]]

-## 📊 Core Web Vitals & TTI Improvements
-
-- **60% faster** Time to Interactive on Meta’s developer portal after adopting RSC (from 3.5 s to \~1.4 s) [[5]]
-- **45% quicker** First Contentful Paint in the same migration [[5]]
-- **50% lower** server response time with Server Components [[5]]
-- **15% improvement** in Core Web Vitals and **23% reduction** in Time to First Byte at Airbnb after RSC migration [[5]]
+- [An experiment at Nordnet comparing equivalent applications with and without streaming SSR](https://www.diva-portal.org/smash/get/diva2:1903931/FULLTEXT01.pdf):
