I got a bunch of fixes i need to commit. I'll try to send out patches this week. They should make things go faster. What is your test setup like? I was able to do 1Gb/s with 0rtt. As soon as I add delay with netem, I could only do ~75Mbit/s. Still investigating why. Also make sure you change the socket buffer wmem sysctl. - : send the line "unsubscribe dccp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
