Regarding EDF.
I've been pushing folks to move latency sensitive computing in ALL OS's to a
version of EDF since about 1976. This was when I was in grad school working on
distributed computing on LANs. In fact, it is where I got the idea for my Ph.D.
thesis (completed in 1978) which pointed

Thanks for the H/T, Dave!
I keep seeing bufferbloat in userspace proxies and tunnels, and think that
the world would benefit greatly from aqm library for applications to use in
order to keep latency under control. Especially if work like encryption is
being done and the results thrown away due

The post persistently points out that openvpn tends to optimize for
one direction only. This is in part due to the large internal buffer
in it. I'd longed to fq it

That might help if the wifi link is the bottleneck, *and* if not too much
buffering is done by the wifi hardware.

Sorry to disagree a bit, but I consider this to be conceptually decent
advice. If a problem can be avoided by a simple behavioral change, recommending
that change seems quite reasonable. Sure, the

I don't know if the Windows 10 updates multithreading problem is still
relevant for many users, but it certainly still affects me as user with
low bufferbloat, low latency, and only moderate bandwidth (50mbit , 4ms
idle, ~9ms loaded)
In any case, I have submitted official feedback to microsoft,
