Meaning: once the result from the forwarder is received, your bind instance should cache it (to a disk file as well) with a long, long TTL. Even if you restart bind, named will pick up the cached information from the cache-file and you should see improvements over time. That's essentially what OpenDNS does for you. http://wiki.apache.org/spamassassin/CachingNameserver has more information on this. Did you configure you local named to cache results from forwarders?

With bind, 3, 4 and all next attempts are successful :) Currently my DNS is so slow, that http://www.google.com/ resolves from the third try. With bind, 3, 4 and all next attempts are successful :)

I can really see improvement in "initial returns" from the moment I typed in a URL until the first packets arrive. That seems to largely stem from the fact that OpenDNS has a lot of sites I hit already cached. Cheers - Tobias Interesting – perhaps you started with a faster DNS connection to begin with?
