The first time you do it you may see something like:

Received 194 bytes from 127.0.0.1#53 in 1291 ms

But if you do it again, and it is working, you should see something on
the order of:

Received 194 bytes from 127.0.0.1#53 in 1 ms
Is it not doing four look-ups;  I would think that takes longer?

First look-up:

;; ADDITIONAL SECTION:
ns1.google.com.         172521  IN      A       216.239.32.10
ns2.google.com.         172521  IN      A       216.239.34.10
ns3.google.com.         172521  IN      A       216.239.36.10
ns4.google.com.         172521  IN      A       216.239.38.10

;; Query time: 1817 msec

;; WHEN: Tue Aug 22 08:21:19 2006
;; MSG SIZE  rcvd: 212

Second look-up:

;; ADDITIONAL SECTION:
ns1.google.com.         172496  IN      A       216.239.32.10
ns2.google.com.         172496  IN      A       216.239.34.10
ns3.google.com.         172496  IN      A       216.239.36.10
ns4.google.com.         172496  IN      A       216.239.38.10

;; Query time: 58 msec
;; SERVER: 127.0.0.1#53(127.0.0.1)
;; WHEN: Tue Aug 22 08:21:44 2006
;; MSG SIZE  rcvd: 212


However, I never see single digit delays!
