One trick when lookups are slow and out of your control is to cache
DNS results with: /usr/sbin/nscd - name service cache daemon
It is easy to try and test:
chkconfig nscd on
service nscd start
If you are trying to debug a name server or set of name servers
turning it off helps:
service nscd stop
or to just turn it off permanent.
chkconfig nscd off
service nscd stop
