Hello, new member here.
First, thank you all involved in making this great piece of software, which
I have already experienced without issues during a couple of months.
Back then, it was on Openwrt, in a TP-LINK Archer C-7 router, bandwidth
capped to 60 Mbps (on the device's limits, but still making Internet usage
much smoother to all users).
Then I moved the router to a debian 10 Celeron J1900 mini-ITX, 4 GB of RAM,
two entry level Gigabit cards.
So far I couldn't get the stable A's in dslreports test I was getting with
the previous setup.
The point is that my Internet has been upgraded from 60 Mbps to 240/20
Mbps. SInce most, if not all, devices are still 100 Mbps, I'm currently
capping cake at 85/18.
I basically "transported" the cake settings from Openwrt to debian,
basically adjusting the speed limits.
I would like to know where I start troubleshooting this, to help identify
what is causing bufferbloat on this new setup.
Follow cake settings, then tc, then network hardware info

Ok, I decided to step backwards, and start from the beginning.
My first goal will be to make sure the hardware is ok, mainly, the network
interfaces.
I reinstalled Debian 10, turned it into a barebones router, and ran the
*speedtest-netperf.sh* script from Openwrt
<https://github.com/openwrt/packages/blob/openwrt-19.07/net/speedtest-netperf/files/speedtest-netperf.sh>,
either from within the router, as well as from my 100/10 notebook.
The results seem to indicate everything is fine:
-
From the server, the test maxes out the Internet link;
-
Fromt the notebook, the test kinda maxes out its interface roof: close
to 90 Mbps in all four tests (I will assume this is because of poor
hardware quality)
I also switched WAN and LAN interfaces, just in case, and repeated the
test, which gave similar results as before.
PARTIAL CONCLUSION: So far so good.
Attached, both results.
*Atenciosamente,*
