Time to use dig or your favorite DNS troubleshooting tool. 

It could be as simple as the first DNS server mentioned in
/etc/resolv.conf is non-functional, very slow or unreachable, and you're
waiting for it or waiting for the timeout in your local resolution code,
before failing over to the next server.

As an alternate to doing test lookups with a tool, you could just
reorder the servers in resolv.conf and/or add a line

options timeout:1

or append "timeout:1" if there already is an options statement, so as to
reduce the timeout.  If I recall correctly, the default would be 3
seconds, which is an eternity on a fast network.
