Interestingly, turns out that seemingly systemd is what is (currently) responsible for turning on fq_codel by default. See:-
https://github.com/systemd/systemd/commit/e6c253e363dee77ef7e5c5f44c4ca55cded3fd47 Be nice to then get that suggested into upstream linux as a default and/or procps for 'non-systemd' booting.

It is still not quite part of fedora´s default either, but is now in arch, (and nearly everyone else downstream from systemd), and has long been the default in openwrt, and at this point, just requires a single sysctl to enable. It certainly could use more widespread testing, perhaps in the next release? d@nuc-client:~$ cat /etc/sysctl.d/10-bufferbloat.conf net.core.default_qdisc=fq_codel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1436945/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
