RE: DNS response times

Hi,

The Squid proxy/cache (http://www.nlanr.net/Squid) has its own caching dns server; no cascading of dns caches between cache servers, only locally. But it might be a good idea to extend squid with this feature.

Our Squid server (1.1beta7) gives a hit rate of 93 % on DNS lookups :-)

Cheers,

Paul

Subject: DNS response times

Hi,

having noticed (like many others before) that DNS lookups account for a
large share of the total overhead of WWW proxying, I fell to wondering:

Given that the Terena project is to improve proxying,
how about a sub-project to improve DNS lookup times?

E.g., how about building a backbone of very-high-level DNS "caches" (one
or two per provider) that pro-actively and cooperatively build and update
a database of (almost) all currently valid DNS entries? Sort of like a
newsgroup of DNS entries, I suppose.

A system like that should improve DNS lookup times a-hundred-fold...

   Day-dreaming,

Andreas Strotmann

PS: I have some statistics stuff to contribute. Was there an e-mail
address of the person collecting these?
