Folks, With 2.6.19rc6 plus the patches from http://wand.net.nz/~iam4/dccp/patches/ it works fine. (The only significant patch here is tx_qlen - all the rest should have no impact). So here are the stats using iperf: Test 2.6.19rc6+ian 2.6.20-acme20 Direct connect 87 Mbits 36 Mbits Through a Linux router (1.2 ms rtt) 36 Mbit 200 kbits (yes that is correct!) Through netem (100 ms rtt, 5% loss) 130 kbits 116 kbits (OK)
I've been trying to track this down to any individual patch and I'm going crazy! With my code (2.6.19rc6+my patches) now I'm getting the same bad numbers as for 2.6.20-acme20 This is bizarre and means that there is something in there very fickle and intermittent... That means I also owe a big apology to everybody for casting dispersion on their code. I'm giving up for today I think as my head hurts!!
