It is very good, or even necessary to have a DNS caching server on the
gateway, however, it can't do miracles.  If the data is not cached and
your real DNS server is slow or unavailable, you still have a problem.

The timeout could be caused by SA's Plugins as well (dcc, pyzor, razor),
or simply CPU or I/O limits.
