This results in your trie having two new run-time costs: 1) More expensive trie insert/delete compared to hash insert/delete 2) An extra list insert/delete to give list of all sockets So connection setup/teardown will be more expensive and therefore our connection rates will be lower. Evgeniy, your ideas are beautiful in theory, but all the details kill all of your non-trivial work and make it useless in the end. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
