So it took 7 times more processors to increase the performance gain by just over 3 on a microscopic synthetic benchmark. That's not impressive at all. And you still haven't shown what happens for the workloads I suggested. A web benchmark, with say a thousand unique clients, would be sufficient for one of those btw. That case has very low dst locality, yet dsts are useful because you'll have about 2 or 3 concurrent connections per dst. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
