I am sure you can get more than 5 messages per second even the 
stations are loaded.  (Well, SUN3s are quite slow at today's 
standard but it got to do better than that.)  I think that the 
problem may be because you are not using the no-blocking option
(there is such a option, right?  iocntl() or setsockopt()) when
using the sockets.  Please check your program and options on using
sockets on UNIX.

PS: I am not ssure about the no-blocking thing, but I kind of
    remember such an option when I used sockets a few years ago.
