I believe Anand was aware of this RFS/RPS thing not available in 2.6.26 ;) Anand, if you have two NICS, you can try to irq affine each NIC to each CPU. Other than that, you could try a multi queue NIC and fairly recent kernel. 2.6.26 has a lot of bottlenecks, I am not sure trying to use your two cores will actually help. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
