As others have mentioned perhaps you are missunderstanding what those
programs do. It will help if you tell us what you are trying to do.
A mini review of the tools in question
Answers DNS requests
Squid and other proxies
Let's say you have 3 users in a network and they all use common sites such
as bsdnes.com or slashdot.
A caching DNS server will cache the IP for the site. Nothing else.
Bandwith/time saved.. minimal.
A caching proxy like Squid will cache content (The actual pages) so there
will be time/bandwith savings because only one user will have to actually
wait to go to the actual site while the rest will get the data from the
The more users using the same sites the better performance gains you will
see from a proxy.
For a single user there may be savings, but I think not as much. There are
benchmarks out there that you could search, but the general rule is that
the benefits of the cache are greater as the number of people using the
same site increase.
Hope that helps clarify a bit.
