Local DNS Cache for Faster Browsing « Ubuntu Blog
You can run a DNS cache on your computer. This will speed up the process of looking up domain names when browsing. The difference is about 30-60 ms for me. Multiply that difference by the number of websites you visit a day for an approximate estimate of the speed improvement. Of course, all this would be worth it if it weren’t for the fact that setting this up is way too easy.

The Public Suffix List
A "public suffix" is one under which Internet users can directly register names. Some examples of public suffixes are ".com", "" and "". The Public Suffix List is a list of all known public suffixes. The Public Suffix List is an initiative of the Mozilla Project, but is maintained as a community resource.

codeblog » paranoid browsing with squid
As Carthik says, the SSH SOCKS option is a great way to quickly tunnel your web traffic. A word of caution for the deeply paranoid: all your DNS traffic is still in the clear. While the web traffic and URLs aren’t sniffable any more, curious people can still get a sense for what kinds of stuff you’re browsing, based on domain names.
