In my browser the speeds are opposite, in both cases the key time is
spent waiting for the web server.<br>
<br>
Case 2: if your DNS server has access to the internet, you will
likely see an increase in speed. There are some test suites to test
the general lookup speeds of servers, try with and without
forwarders. I guess your numbers are better without but nobody will
notice any difference in real life. In some cases there are some
blocking of specific sites in place, those you will lose with no
forwarder.<br>

What a delightfully vague requirement. :)<br>

I would push back a bit on exactly what problems are
attempted to be<br>
solved here. The BIND defaults are about as efficient as
they can be,<br>
especially so in later versions.<br>
