It should be instantanious. Try telneting directly to the nntp port
(119) on nntp.dragonflybsd.org and issuing a few commands manually.
e.g.:
idiom:/home/dillon> telnet nntp.dragonflybsd.org 119
Trying 216.240.41.25...

If that goes fast then try going through your normal program, but
perhaps run a ktrace on it to see where or why it is stalling, and/or
a tcpdump to observe the network traffic on the port while it is running,
to try to figure out where the latency is occuring.
