If you run `ip addr show`, you should be able to see. For me, that shows:

2: enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000

fq_codel is the default on linux, osx, and ios now. It "just works" at line rates. It's also part of the linux wifi stack for a half dozen chipsets. It's not visible via qdisc as it's at the wifi layer: https://lwn.net/Articles/705884/ but works brilliantly. No configuration needed, all the noise you hear on the internet about cake and fq_codel is the costs of setting up a shaper.

If more ISPs ran at the line rate of the interface, and shipped fq_codel or cake by default (it's the shaper that costs 95% of the cpu, not these algorithms), our intertubes would be a lot better. Sadly most are shipping 7+ year old kernels.

Bit of a late reply, but thank you for your work on bufferbloat & better queuing and shaping.

It makes such a difference to internet usage!
