Hi Dave,
This isn't specifically cake related but I figured it could be interesting,
especially as these are from a location where I've been investigating setting
up something with cake. These are statistics from a relatives location where
they only have a DSL line from CenturyLink available to them. There's a little
Debian based VM I setup for a couple random things so I was able to run flent
from that. They have a EdgeRouter X serving as the router so they can at least
take advantage of fq_codel through the routers Smart Queue feature. I ran a
quick speed test, then ran flent without sqm, and then with sqm. Sorry if this
gets a bit long and hopefully it stays readable.

Subject: [Starlink] an rtt_fair test?
if anyone has a bit of spare time this holiday, I'd like to collect a few
results from various networks around the web this week, not just on the turris.
Example command line and outputs here:

I tried to build a better future, a few times:
