What sort of workloads are you doing where 60ms extra time on your DNS lookups is an issue?

I naively assumed most OS + routers cache DNS queries so that your typical sites will not even require a lookup. Or is that a bad assumption?

I switched from Adguard Home to Blocky because I noticed how much faster page loads were on Blocky. I've configured it to cache any query I resolve more than once in a 24 hour window. This makes most of my page loads really, really fast.

Adguard also has the ability to cache. But I haven't seen it to significantly speed up my page loads. The default resolution itself is much slower on Adguard + Cloudflare DNS compared to Blocky + Cloudflare DNS. So this makes Adguard double whammy.

DNS records commonly have cache lifetimes (“TTLs”) of a few minutes. It would be an error to cache those for much longer.

Nothing interesting particularly, but cached + faster DNS resolution is usually perceptible in general web browsing.
