Just to add my two cents worth...

We use a 450MHz PIII with three 3Com 905B cards for routing here. The box is
connceted with full duplex in all ends.

One afternoon it did 9.5 MB/s in one direction and about 2 MB/s in the other,
in average over five minutes.
(Stats from MRTG from one of the switch ports to which the machine is
connected)

Packets were mainly large I assume (probably several people during file
transfers). Still a decent number.

It's two IDE disks are configured in RAID-1 (software), so the one time when
a disk died on us, we could wait until a convenient time to take the machine
down. So besides from being pretty fast, it's also pretty damn stable.

I'm sure that there's a need for Cisco when it comes to very large bandwidth
routing, or routing between a very large number of interfaces. But here it
will be a cold day in hell before we replace this box with a Cisco, given the
price for a comparable router from them. (Btw. how people could accept to have
unencrypted telnet access only to their backbone routers is beyond me - I know
this is improving now).

Cheers,
