Some real data, these are test results for throughput (max zero loss rate) for the Novell multiprotocol router running on a 486 box. these results are for ethernet to ethernet through a T1 line, the limiting factor is the T1. There are more sults on hsdndev.harvard.edu in pub/ndtl. Small packets run at about a half T1, large packets at about 75%. The limit is not in the PC it is in the serial line interface. (the same PC can run at more than 50Mb/sec fddi to fddi.)
