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)
Note that this test did not involve full BGP. Given the problems that used to occur on some name brand routers when BGP took up too much CPU, I would be careful extrapolating these results if you are planning on running full BGP. As the paper itself says, " In a real-world situation the device might be running BGP, with a full routing table. This will surely affect the performance of the device." Regards Marshall

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").
