There are no standards in terms of most metrics. TTFB of 638ms is a decent but can be reduced to around 300+ms. I don't think a TTFB of 3ms is feasible.

If you need detailed response or specific help to your website, you will have to provide more information and links to WPT runs. This will provide more context for your query.

Patrick is aware there is a problem with the target FBT especially when there is a CDN involved. He'd promised a fix.
