safari delays before page starts loading

1. it always happens if first time visiting a URL
2. the subsequent visits on the same URL/sub-URL will be normal
3. come back to the visited URL some time later, it delays again.

Looks like after AG validates everything on a domain (which takes time), it then gives a fast track pass to the subsequent visits until the pass expires, something like that.

If I turn off AG and use those browser-extension AD blocker like ABP, uBlock Origin, with the exact same filters subscribed, I don't have this issue at all, pages always start loading immediately.
