I have a question about total system throughput on a general PC running linux.

Say I have a 2ghz athlon 64 based single processor system with plenty of ram and loaded with 32-bit linux and any linux based routing software.

I have 5 gbit ethernet cards in the server each one going to a subnetwork that will be serving several hundred clients. I realize this is a very generic question, so I'm only looking for a estimated range, what kind of throughput can I expect across the entire system? How about a system with PCI Express slots instead of just PCI?

I know something of this scale should have actual network ASICs in it, but for this application it won't.

input?
