Re: [Bloat] will starlink have bufferbloat?

[Dave Taht]

 Mailing lists seem to be no longer effectively indexed by Google, so I've
been trying various alternative means of having our issues show up in the
world.

That Reddit post got a bit of traction, as the author of "delay is not an
option" showed up, and it does help that I'm pretty passionately interested
in the overall subject... How a service intended to carry internet for
millions is actually going to work has had too few questions of it asked so
far.

There is some guaranteed staleness in the document.

Unless you are in a hurry, I'm planning to do a fresh install on new kit in
a few weeks and will update then with current experience. I'll post them
then...  The router uses a different bootloader/flash arrangement, and so
is a bit of a hassle relative to most routers.

If you are in a hurry, I'll email you the document I have (my son
successfully followed them), so they are not complete rubbish.

Re: [Bloat] [Make-wifi-fast] Does Ubiquiti Unifi have bufferbloat and unfair/bloated WiFi scheduling?

[Jim Gettys]

I'm running OpenWrt on the Unifi AC Mesh access point; (it has an ath10k
chip). It sits on a pole above my ridgeline and provides service to my
house and yard.

I dunno what the state in the Ubiquity provided firmware is.

OpenWrt has the nice new wifi code in it, which indeed really fixes
bufferbloat.

As I also have an ath9k in my laptop and run Linux, I now even do
(previously insane) things like have my scheduled backups go over WiFi while
teleconferencing, and I'm a happy camper.

Getting OpenWrt installed on it the first time is a bit of a chore; I have
some notes around someplace on what I learned when I did the install.

Re: [Bloat] [Cerowrt-devel] will starlink have bufferbloat?

[David P. Reed]

Sorry, I can't help - I never spend time or effort on Twitter, Reddit, etc. 
because I see no value and lots of problems in doing that.
 
Musk probably wouldn't love my views on most of his companies, anyway.
I hope he gets something right on this one.

[Bloat] Does Ubiquiti Unifi have bufferbloat and unfair/bloated WiFi scheduling?

[David P. Reed]

I have been chatting with a startup in the Multi-User Dwelling networking 
operations space, and they seem to really be attracted to Ubiquiti Unifi 
systems. I can't blame them for wanting a comprehensive and evolving system.
 
But on the questions related to bufferbloat and making wifi both low latency 
and fast, I really don't know much about these products. (I have a Unifi 10 
Gb/sec switch as my home/lab fiber backbone, but that's not really relevant to 
answering this question).
 
So, since you, Dave, and others have been talking about real-world fq_codel 
etc. and faster wifi scheduling, does anyone know what the status at Ubiquiti 
is?
 
I know some here run OpenWRT/LEDE on Unifi APs, but that's not my question, 
really.
 
Any knowledge out there?
 
(I'd like to recommend that they run some actual load tests - flent RRUL, etc. 
- but I think they might need some help).
Personally I have no stake whatever in their use, but I'd love to get someone 
to start solving the bloat and queueing/scheduling problems.

Hi Dave,

Google Alerts today found your Reddit post 
(https://www.reddit.com/r/Starlink/comments/brn6gg/will_starlink_have_bufferbloat/
 
)

It also provided a link to a Slashdot post that seems to have been marked as 
spam... https://slashdot.org/submission/9718636/will-starlink-have-bufferbloat

Was this your original submission? In any case, I upvoted it.
