Or another way to say it might be, when sending data over a TCP connection, the sending side queues up data in order to send the largest packets possible, thus necessitating the fewest ACKs. When you usleep in the middle of such a queuing operation, the algorithm has to assume you're done sending for the moment and empty its queue, even if you have more to send. That results in more packets, more ACKs, more latency issues, and less bandwidth for you to use. _______________________________________________ p2p-hackers mailing list [email protected] http://lists.zooko.com/mailman/listinfo/p2p-hackers
