Harald gave a talk about that 2 years ago, maybe it's still somewhat applicable: http://www.heinlein-support.de/upload/slac/network_performance.pdf Also you might want to contact the guys from the Bifrost distribution: http://bifrost.slu.se/index.en.html They seem to be testing for this sort of performance regularly, and I've gotten hold of some of there stats last year thanks to the help of a friendly Dane: http://robur.slu.se/Linux/net-development/experiments/2008/080623.tyan2927 I've also done some rather unscientific tests myself and apart from best sticking with the two onboard PCIe Gigabit NICs (Intel, Broadcom) of quality server boards and getting the best main memory performance you can get hold of, the main thing seems to be L2/L3 cache size, so in my tests Intels current CPU line slightly outperformed current Opterons last summer, but traditionally most people advised the use of Opterons because of there better SMP memory performance. But I was only interested in 1GiE-NICs tied to one CPU core each at the time, so this might be meaningless in a multiqueue scenario with 10GiE NICs. -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
