High latency setting optimization

[Daisuke HIGASHI]

Hi,

Forwarding all queries to other caching resolvers with low RTT to auth servers
(e.g. your ISP's resolver or 8.8.8.8) should improve resolution time.

But that wouldn't be optimal because Unbound chases CNAME chains
even if it forwards all queries to other resolver [1]. For more performance
use caching-forwarder-only software (i.e. dnsdist or dnsmasq) instead
of Unbound[2].
