I don't know the answer. I think each system would have to be qualified
including NIC, operating system, motherboard, etc.
My current high end systems use an Intel Quad port server adapter
<http://www.intel.com/content/www/us/en/ethernet-products/gigabit-server-adapters/gigabit-et-et2-ef-multi-port-server-adapters-brief.html>.
I found the server adapters to be worth the extra money.
Also, for iperf 2, a single traffic stream uses two threads, one for tx or
rx and one for accounting and reporting. I found 8 CPU cores to 4 NIC
ports to be a good ratio.
