Are you talking about TTFB on which path exactly?

TTFB for a static asset (like a JS file, or a JPG user upload) will always be fast using a CDN, as latency only of the multiple PoP will help with it.

TTFB of dynamic routes in the other hand makes no sense to compare, as our `DISCOURSE_CDN_URL` doesn’t cover those anyway.
