A lot of performance guides recommend a caching dns on the squid server,
as it
reduces the load on the network and your dns.
A caching only bind is easy to setup, at least if you use a precompiled
package, so I installed one just to check the difference.
In my case it did not really improve performance measurably. Depends on
the load, I guess. System load is average (8...10GB traffic/day).
The seperate DNS used before via /etc/resolv.conf (and I still use them
now as forwarders) have a fast network link to the squid machine and a
decent performance.
It may be different if you have to use an probably overloaded ISP dns.
