Yes, PIE does apparently work better here than fq_codel. This is a
subjective judgement. I have stopped using RRUL.

Thank you.
Are you still using ADSL2+, Sebastian, or have you moved to fibre?
Yes, I am still on ADSL2+ (16M downlink 2.5M uplink); I hope to switch
to VDSL2 soon (50M down, 10M up), since real fiber is not offered where I live.
For completeness I have shaped down and up link to 95% of the raw link-rate,
and use simple qos, with tc_stab, link layer ADSL, overhead 40, and that seems
to work well in my setup. My link is quite robust, that is I get a number of
FECs but only few CRCs (and FECs do not require retransmission of cells and
thus do not impact the effective link speed).
I have one question, does PIE work better for you than fq_codel on your
test load (i think you try to watch some videos while up- and downloading is
ongoing)?

I have been using PIE instead of fq_codel for approximately 10 days. It works
well.
Intrigued by your report I went ahead and tested simple.qos with
fq_codel and pie (cerowrt 3.10.18-1) with rrul against demo.tohojo.dk:
/netperf-wrapper -l 300 -H demo.tohojo.dk rrul -p all_scaled -t my_silly_name
Pie (with the default target of 20ms(?) shows around 120 ms ping delay
(fq_codel shows 45ms) also the average downlink with fq_codel is roughly 10%
higher than with pie. So at least in that test fq_codel seems better than pie.
That said, compared to ping latencies up to 300ms (my primary router somehow
restricts ;agencies to roughly 300ms) with no AQM, just rate shaping with HTB,
pie still keeps the internet more useable.
Should it?
I think its designers wanted it to be a competent disc, so I guess it
should :)
Has PIE been optimized for ADSL?
Best Regards
Sebastian
