In my browser the speeds are opposite, in both cases the key time is spent waiting for the web server.
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. > > Larry > > > On Mon, Nov 26, 2012 at 11:39 AM, Doug Barton <do...@dougbarton.us > <mailto:do...@dougbarton.us>> wrote: > > What a delightfully vague requirement. :) > > I would push back a bit on exactly what problems are attempted to be > solved here.
