There are two things that usually result in a speed up.
The first thing is enabling ncsd, a system daemon which caches DNS results and 
calls to the user data base (user rights, etc)
It is a service provided by the system itself, i.e. it will "sit" below the 
basic C-library all applications are using, thus benefit all applications.

Another thing to try is disabling IPv6 based DNS lookup, see
