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."

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: [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").
