A good PCI machine (like a 100-MHz Dell I have in the lab) with good PCI interfaces (like the DE500s we have in that machine) can forward about 15,000 minimally-sized packets per second (all to the same destination, but my tests indicate that this shouldn't matter). That comes to about 7.7 Mbit/s. Not as fast as we would like, but well within the envelope for most uses. (This load is from an input stream of 18,000 packets per second over Fast Ethernet.) For larger packets, the rate goes down somewhat. -GAWollman -- Garrett A.
