It sounds like the problem is the broadcom chipset (earlier versions of)
combined with airdrop using the chipset to talk on two channels at the same
time,
which destroys wifi throughput. and not much to do with buffer bloat.
At least that is the TL;DR of a long article posted in the comments.

Quite possibly. Then the first part of my message ("It used to work. You just upgraded to a new OS. Apple owes you support.") remains true.

But a plug for DSReports Speed Test never hurts :-)

Hi Dave,

Yes, it's very cool. Justin at DSLReports is doing something similar with websocket pings (I think - he'll respond if I'm wrong) which are pretty lightweight and therefore pretty good tests of latency. (Not quite as close to the metal as an ICMP Echo, though.)
