Hi,

correct, I've left egress on 4000 (I thought I should test only ingress
first), but when I did the test with youtube + torrent transfer, I've had
set upload to very small number (I think 10 kbytes/s).

Yes I have DSL line (VDSL2 as I've read ISP info), I'll try to set the
linklayer option on ethernet with overhead of 8, like it says on
http://www.bufferbloat.net/projects/cerowrt/wiki/Setting_up_SQM_for_CeroWrt_310
I have linux machine so I'll install netperf-wrapper and test things

sqm configuration:

root@cerowrt:~# uci show sqm
sqm.ge00=queue
sqm.ge00.interface=ge00
sqm.ge00.qdisc=fq_codel
sqm.ge00.script=simple.qos
sqm.ge00.qdisc_advanced=1
sqm.ge00.ingress_ecn=ECN
sqm.ge00.egress_ecn=NOECN
sqm.ge00.qdisc_really_really_advanced=1
sqm.ge00.itarget=auto
sqm.ge00.etarget=auto
sqm.ge00.linklayer=none
sqm.ge00.download=3100
sqm.ge00.upload=4000
sqm.ge00.enabled=1

Thank you guys,
Dane
