No need to fiddle with any scripts now.... I guess of largest import here, underlying the gui, is that I had a chance to deeply look at simple_qos.sh. There are several bugs in it, that appear actually in the underlying tc subsystem.On ingress, the priority queue was not being used properly, and a few other things were odd in ipv6. Out of frustration with that, and based on the data we'd got back from cablelabs, I wrote the simplest possible rate limited fq_codel implementation, using a reduced number of flows and a single tier of htb only - and that works surprisingly well. It's called "Simplest" in the new AQM screen. Give it a shot. Secondly, the exercise of writing that and comparing it to the simple_qos s= cript .... seems to have exposed a bug in htb at low bandwidths. http://snapon.lab.bufferbloat.net/~d/dsl384k-htb-bug.svg Here I was trying at 384k up and 8Mbit down, and the middle portion of the upload graph there is kind of... impossible. At higher rates I haven't seen this happen. --=20 Dave T=E4ht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.= html
