Some stats (on two different machines at least with dummy) on a system with low # of processes: ~80% of the time - we exit the loop because of packet quota ~1% for both need_resched and jiffy ~19% simply because there were less than quota packets Note: we do use a jiffy check on net_rx_action() but i suspect we never ever hit it. cheers, jamal -- 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
