Ok, "to a zeroth approximation". That said: it depends on what you're trying to measure, as has been pointed out before: the entire *point* of edge caching is "to get all that duplicated traffic 'off of the Internet'," no? > > As for your DNS question: the interior query isn't, per-se, but the > > repeated one from your resolver/proxy *is*. > > I don't think the type of packet (DNS, HTTP, SMTP, etc. or even TCP, > IP, ICMP) should matter. The rest of those are generally not application-level proxied the way DNS is with most consumer edge NAT routers. Cheers, -- jra -- Jay R.
