Hi Dave,

when I use tcp_12down instead of tcp_ndown I end up with something looking sane (see attached image?)

Also:
Summary of tcp_12down test run at 2016-11-20 20:16:54.350770:

                             avg /       median          # data pts
 Ping (ms) ICMP   :        54.08 /        53.75 ms              351
 TCP download avg :         3.52 /         3.57 Mbits/s         301
 TCP download sum :        42.24 /        42.79 Mbits/s         301
 TCP download::1  :         3.50 /         3.63 Mbits/s         301
 TCP download::10 :         3.55 /         3.61 Mbits/s         301
 TCP download::11 :         3.57 /         3.62 Mbits/s         301
 TCP download::12 :         3.54 /         3.66 Mbits/s         300
 TCP download::2  :         3.51 /         3.61 Mbits/s         300
 TCP download::3  :         3.55 /         3.61 Mbits/s         301
 TCP download::4  :         3.59 /         3.67 Mbits/s         300
 TCP download::5  :         3.46 /         3.55 Mbits/s         300
 TCP download::6  :         3.49 /         3.60 Mbits/s         301
 TCP download::7  :         3.50 /         3.59 Mbits/s         300
 TCP download::8  :         3.48 /         3.57 Mbits/s         301
 TCP download::9  :         3.50 /         3.58 Mbits/s         300


looks fine. But maybe tcp_12down is not exactly doing the same as tcp_ndown… I tested from a laptop attached to one of the omnia’s lan ports (omnia’s wan is connected to the lan port of a LEDE r2222 wndr3700v2 with double NAT).

Best Regards
Sebastian

Has the omnia got this problem?

If you hit it with more than one download flow in netperf(flent), all
successor flows still starve.

I was under the impression a fix (also adding BQL) had arrived for
this problem in mainline.

filed a bug on it just now, I should have done so long ago.
