This might be of some use, it's a document written by one of the AMS-IX engineers, it's a little aged (almost 2 years old) so there should be some improvement in the numbers, but it might give you some insight in the bottlenecks when pushing a Linux server to it's max (10Gigabit in this case)

I see the Intelsrecommended by Mike have dual ports on one board (the docs say "Two complete Gigabit Ethernet connections in a single device • Lower latency due to oneelectrical load on the bus").
