I would certainly like to have a standard way of getting these
statistics, through the dns, perhaps one unified with whatever bind
and unbound use (or don't use.)
Not a lot of people seem to be aware of why dns caching forwarders are
so great, although benchmarks like namebench against your chrome or
firefox cache are quite revealing, parsing huge network captures as
I am presently to try to get a grip on timings for dns/response
pairing is a pita and not router centric.
Do check out namebench, it's pretty cool. It does bug me that in tests
against the alexa top 2000 that it invariably selects some other dns
server besides your local one as being the "best", because it has
the best average - as if you regularly go to websites in timbuktu and
care about the response time more than, say, google.
Example against alexa top 2000 with a fresh cache:
It is much better to test against your more common query set, which I
don't have a snapshot of on that site presently - usually 40% or more
of queries are resolved in a ms, 30% or so via your ISP in under 20ms.
I'd love to see people posting namebench results from against their
firefox/chrome caches... it's in apt on ubuntu at least....
the version I have is buggy, you have to hit control-C at least once
for the gui to come up.
