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)

The boxes (3650s) came with Broadcom BCM5708 on-board, but I push most
of my traffic over these:
1c:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit
Ethernet Controller (rev 06)
Subsystem: Intel Corporation PRO/1000 PT Dual Port Server Adapter
Flags: bus master, fast devsel, latency 0, IRQ 58
Memory at c7ea0000 (32-bit, non-prefetchable) [size=128K]
Memory at c7e80000 (32-bit, non-prefetchable) [size=128K]
I/O ports at 6020 [size=32]
Capabilities: [c8] Power Management version 2
Capabilities: [d0] Message Signalled Interrupts: 64bit+
Queue=0/0 Enable+
Capabilities: [e0] Express Endpoint IRQ 0
Capabilities: [100] Advanced Error Reporting
There are four Intel ports in the boxes, so traffic may or may not
stay on the same PCI-X card depending how things are flowing.

David: May I ask which NICs you use in the IBM boxes ? I see the Intels
recommended by Mike have dual ports on one board (the docs say "Two
complete
Gigabit Ethernet connections in a single device • Lower latency due
to one
electrical load on the bus").
