If its that noticeable, your DNS server is sick, tired and/or hungry.
Find another one. That's the core problem.

Secondly, I am pretty sure recent versions of Chrome (and maybe FF) do
indeed cache DNS on Linux. I am using the alpha version of google
chrome, and I am 99% sure there is some DNS caching going on.

Also, its trivial to install a caching DNS server in Linux, something
like 'sudo apt-get install bind9' or somesuch, which might also
workaround the server problem.

Caching DNS has good and bad aspects. I tend to not prefer that kind
of thing in favor of fast server response times.
