Time to First Byte (TTFB) is the first time metric to fix.

In the image, we can see a TTFB of 1.88s in the field data, the rest of the time metrics, like FP, FCP, or LCP, start after this time.

I still don't understand why using Cloudflare in front of Netlify allows for a much better and stable Time To First Byte (TTFB) than Cloudflare Pages or Netlify alone… 🤷‍♂️

TTFB for static sites should always be very low.

Pay attention to the Time To First Byte (TTFB), which precedes user-centric metrics

🤬 Ecco l'ennesima affermazione data con troppa leggerezza..
🤔 #http3 non sarà un segnale di ranking, e da solo non ti farà aumentare il fatturato dell'#ecommerce..
🚀 Però può ridurre il #TTFB, e questo impatta su #LCP e su altri Web Vitals. Aggiungi altri dettagli per ottimizzare la risposta del server, le richieste di rete e i ritardi di caricamento e di rendering e fai volare la #UX.
🧐 Quindi di cosa stiamo parlando?
