I'm on vacation, so I can't do a ton of testing, but it seems like in the
last ~2 days, my DL speeds are lower (<160Mbps, generally 90-110Mbps), but
download-induced bufferbloat is also greatly reduced (Latency generally
<60ms, with small spikes up to maybe 150ms more rarely -- much better than
to up to 400ms I was seeing before).
I confirmed the same behavior with one other list member, has anyone else
seen similar?

I will be able to test perhaps in 6-10 hours as I'll be getting the system online hopefully.

I have fired off a new string of tests. should be done in an hour.
I don't know if budic has sqm on or off at the moment.

Hey Dave, how’d those tests look yesterday (sqm enabled though) vs today (disabled)? Looks like my dishy upgraded to
4990ce8d-5028-4e51-a015-e9ab1b1ebe1a.uterm.release
around 4:30AM CDT this morning.
Nathan, did you get a chance to check versions or uptime? Probably worth tracking if we’re looking for performance changes.

Dear Darrell:
Toke ended up writing a new test that we haven't deployed yet
https://github.com/tohojo/flent/commit/ec5dd227cec7f0b8316a7e5c8551fd44c4f9a985
which works for the flent tests (like rrul) that use irtt. Install
flent from git... Try a rrul test from any location in the cloud, or
at home, or over wifi or 5g to fremont.a.taht.net (one of my
measurement servers in the cloud)... or dallas.starlink.taht.net
A dishy is available without sqm on between 1AM and 6AM PDT at
dishy.taht.net (through an ipv6 wireguard tunnel. (you are
d2.taht.net)
Moving forward, simplifying things (single flows) and since irtt was
not used by our tcp_nup and tcp_ndown tests, a new one "nup" is under
development which has a few new things like SCE support.
I do have some data on you from today from my cloud, but hey, if you
have energy... please try out something like
flent -H dishy.taht.net --socket-stats --step-size=.05 -t
'whateverthetestcondidtions" --irtt-sampling-interval 3ms -l 100 rrul
and let us know what you find? (the flent-gui can generate plots, you
can also output plots from the command line) The tcp RTT plot is my
favorite.

My dish has not been upgraded yet, I'm still on
a4908729-5051-4d3b-aacc-446ef9b26cdc.uterm.release
My "obstructed" seconds keep creeping up, was 0 for a while, then 0-4s for
a while, now up to ~55s
