LCP 3.6s -> 1.9s with streamed SSR
The shop buffered the entire server-rendered HTML before sending — TTFB waited on the slowest product API.
— Switched to streaming: shell + <head> flushed at 180ms, product grid streamed in via Suspense.
— Browser started preloading hero + CSS 1,400ms earlier.
TTFB: 1.4s | 0.18s
FCP: 2.1s | 0.6s
p75 LCP: 3.6s | 1.9s
Takeaway: flushing the <head> early moved LCP discovery up 1,400ms — same total server work.
