When is an ethernet full?  We have a campus backbone composed of a
chipcom  10 Mbs ethernet over broadband and a UB 5 Mbs ethernet over
broadband (buffered repeaters).  The UB and chipcom networks are bridged
to form one logical networks.  According to our Network General sniffer, 
we constantly maintain about 10-15 percent utilization or (300 - 1000
packets per second).   How much more traffic can this network support
before performance falls off measurably?  Any ideas?  

Thanks,
