Here are some figures retrieved from merit.edu, thanks to Scott Cattanac:

Service			  port	  # packets   % month  #bytes       %bytes
J91irc                    6667     50541247   1.316    3942709477   0.640
F91irc                    6667    107960902   2.776    8849122531   1.397

So Paul Martins figures are pretty much correct in terms of # of packets.
However, if we look at bandwidth, irc only accounted for 1.397% of total bytes
sent on the NSFnet.

jjones@uiuc.edu "They called him a genius, a botanist, a demon, a philosopher, a
                 practical joker, an eccentric, and a visionary.  No wonder he 
                 was such a great engineer."
