Use caching on the initial request.
Sorry but without more info I cant give a more precice recommendation.
use static caching on your origin, or Cache Everything at Cloudflare.

Perfect would be: use both and clear cache on content change.

TTFB does not have anything to do with sitecode (unless the request/URL is completely dynamic)
The bad TTFB is in first place a origin Server problem, as Cloudflare by default does not cache HTML responses. But the problem can be concealed with Cache Everything like said.

Thanks for answer!

You are welcome.
Keep in mind that the TTFB is always the first response from the Server. To have a worldwide perfect TTFB you will want to use Cache Everything, but dont forget to purge the URLs that changes. For Wordpress there are plugins which are doing this automatically.

Thanks man, lots of information, te get head a round

Can you tell me where is “Cache Everything” option in free cloudflare panel…

I Have:

  1. Argo Tiered Cache enable
  2. Caching Level is standard

You will have to activate it by a PageRule:

But handle with care, it will litterally cache everything, as the name says, and you will have to purge the cache yourself on changes to make them take effect.
