with LWN and an audience of aficionados.
The core community is aware of what we've done, but in my view we
haven't converted "grandma". Grandma, as well as a whole bunch of
ordinary engineers and partners of engineers, are dependent on
debloated performance because they're working at home now, and
competing with granddaughter playing video games while they're trying
to hold a video call.
Right now, my colleagues at work suffer from more than a second of
bloat-related lag. They therefore tend to speak over each other on
con-calls, apologize, start again and talk over each other, again.
After a little while, the picture becomes a distinctly silly one: a
bunch of grown adults putting their hands up and waving, like little
kids in school. No-one has called out “me, me, teacher” yet, but I
expect it any time.
I propose we show the results in terms that we can explain to Grandma,
specifically concentrating on functioning VOIP. I just upgraded to
Fedora 31, and the networking is absolutely stock, so I make a perfect
victim/guinea-pig (;-))
Who's interested?
Are the risks and tradeoffs well enough understood (and visible enough
for troubleshooting) to recommend broader deployment?
I recently gave openwrt a try on some hardware that I ultimately
concluded was insufficient for the job. Fairly soon after changing out
my access point, I started getting complaints of Wi-Fi dropping in my
household, especially when someone was trying to videoconference. I
discovered that my AP was spontaneously rebooting, and the box was
getting hot.
I am also wondering about what features will be lost if/when the device
is flashed from the commercial firmware. Does openwrt have access to
all of the available Wi-Fi 11ac rates, and how does rate control
compare? The commercial devices offer proprietary media/device
prioritization settings; does CAKE/SQM outperform them? Many commercial
APs or mesh systems have smartphone apps with features like parental
controls; that kind of control will be lost. What about 11ax support?
