The post covers key performance metrics (FCP, TTVC, TTI, hydration success rate), the implementation of Suspense boundaries with NodeJS streams, a custom data streaming abstraction to sequence server state before markup chunks, and client asset preloading to reduce time-to-interactive. Challenges addressed include timing-related hydration errors, performance overheads from repeated stream transforms (solved by switching to object mode), a React 18 context-change bug causing excessive re-renders during hydration (mitigated via unstable_scheduleHydration), and intermediate proxy buffering (resolved with X-Accel-Buffering headers and compression middleware flushing). The rollout used conservative A/B testing over several weeks with guardrail metrics. ## Full article daily.dev links to this article rather than hosting it.
