Routing in software on a UNIX platform is generally dependent on a number of
factors, all of which have to do with how much processing need be done.
A router which is perfectly capable of 100Mbps forwarding of unidirectional
large-packet (1500 byte) traffic might easily be slagged by 10Mbps of small-
packet (64 byte) traffic. That's because the first case is only about 8000
packets per second and the second case is more than double that, at nearly
20,000 packets per second.
Of course, adding things like firewall rules will also affect overall
