It took a while to find the right entry point, and sure enough, it was not calling the right thing on udp. Dumb quick patch: http://snapon.lab.bufferbloat.net/~cero3/fixtransmission.patch So, great, I could test what I wanted. I have to admit I thought diffserv4 put CS1 in class 3? (haven't looked) (seems more likely we are not matching tos properly in the first place. Because diffserv8 is mostly class 0 also.) root@ranger:~# tc -s qdisc show dev eth2 qdisc cake 8011: root refcnt 9 bandwidth 10Mbit diffserv4 flows raw Sent 316759388 bytes 245396 pkt (dropped 10653, overlimits 456732 requeues= 0) backlog 39088b 27p requeues 0 Class 0 Class 1 Class 2 Class 3 rate 10Mbit 9375Kbit 7500Kbit 2500Kbit target 5.0ms 5.0ms 5.0ms 7.3ms interval 100.0ms 100.0ms 100.0ms 102.3ms Pk delay 86.8ms 20.3ms 192us 291us Av delay 18.8ms 6.5ms 3us 4us Sp delay 4.4ms 1.1ms 3us 4us pkts 219623 36390 2 61 way inds 25724 427 0 0 way miss 2719 2126 2 27 way cols 0 0 0 0 bytes 289564164 41102703 180 7131 drops 10577 76 0 0 marks 0 0 0 0 qdisc ingress ffff: parent ffff:fff1 ---------------- Sent 23422815 bytes 204407 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 --=20 Dave T=C3=A4ht worldwide bufferbloat report: http://www.dslreports.com/speedtest/results/bufferbloat And: What will it take to vastly improve wifi for everyone? https://plus.google.com/u/0/explore/makewififast
