Umm... 32bit/33mhz PCI has a maximum bandwidth of 132 MBytes/sec.
Thats 1056Mbits. (generously) -300 for ATM, -225 for FDDI, -115 for
FastE and -3 for the 10bt (internet link is 1.1Mb) that comes to...
643Mbits/sec for the network links. There's still almost half of my
PCI bus left. Not that I *EVER* saturate any of those links anyways
(only FastE and the inet link are up right now, I need more fiber to
bring the rest online).

Its a 600 Celeron with a 66mhz memory bus and 128mb ram. It works
fine for me so far. I've seen less route more data.
