Dear all
I have some contradictory results on my WiFi link. I run flent's rrul test
using several bufferbloat mitigation algorithms, and see that, compared to
FQ_codel, TCP BBR, etc., a simple prioritized ACK works the best. Why is
that I have no idea. I also am not clear as to why using BBR on the client
end increases the download throughput, but not upload (still doing worse
than prioritized ACK on cubic in download anyway). Attached please see the
plot.
What am I missing?

My setup is pretty simple. I am on WiFi on my PC, and run flent on an
Ubuntu VM on a virtual machine, and connect to netperf.bufferbloat.net. All
configurations are done on my VM end of course.

Any help/hint would be appreciated.

Thanks a lot
Best
Azin
