Somehow I missed the majority of this thread. Was it posted to
mofree-unix?

You can saturate a 100MBit network with just a P100, so any 400MHz
processor shouldn't have any problems. And once you've saturated the
network, you definately have a bottleneck at the network. :-)
Due to the way that SMB works, and since neither FreeBSD nor Linux (as
far as I know) have support for port-bonding yet, the best bet is to
install a Gigabit Ethernet card and attach the machine to an
appropriate switch. You can get a good GigEther card for about $300
these days, and a switch module to go with it for a bit more. Since
you can theoretically get 10 times the performance of Fast Ethernet,
or more realistically 5 to 8 times the performance (especially when
talking to 10/100 devices which have a maximum 1500 byte MTU), the
price is right.
For FreeBSD, I would recommend any card based on the Alteon Tigon-2
chipset. Cards based on the Tigon-2 chipset include the SGI GigEther
cards, the NEC GigEther cards, the DEC EtherWorks/1000, the 3COM
3C985B (note the B revision!), NetGear GA620, and the Alteon ACENIC.
The NetGear is probably the least expensive, but it only includes 512K
of SRAM for buffering, while the more expensive cards can offer 512K
to 1MB or more.
