I have been working to build a new router for a customer and have had access to a pair of Spirent SmartBits SMB-600 with gigabit interfaces. This gave me the opportunity to do some testing. The machines available are Dell PowerEdge 860's with "80557,Xeon 3000 Conroe,3060,LGA775,Burn 2" processors. I tested with the onboard bge interfaces and thanks to Dave some em NICs as well.
The testing shows that with a single processor kernel for any average packet size above 767 bytes you can easily saturate a gigabit network interface forwarding packets. I was able to achieve close to 300k pps in any configuration I tested. Surprisingly with small packet sizes, amd64 did slightly better than i386 achieving a maximum of of 347,812 pps with an em NIC. Until the interface was saturated, latency remained low at less than 500 microseconds.”
