On the system under test I started four ttcp sessions: two senders and 
two receivers (the second one on a non-standard port). One pair for 
each port (device). I'm not sure, to which degree the device was 
saturated. It certainly should have been, since the remote hosts are 
capable of line rate, but I found the sending ttcp sessions on the 
system under test to be slow, as long as traffic was incoming.
