I would certainly like more folk to analyse fq_codel, particularly in
the context of TCP mice and what we call ANTs these days. It seems to
be really excellent, but I too haven't had much time to look at it,
yet. It certainly does an even better job than codel of allowing
sparse streams through in my own testing, and I run it by default on
my laptops, wireless gear, routers and desktop at present. Under heavy
load things like cerowrt and ssh and other stuff like mosh, remain
incredibly responsive.

With ponies that good, there has got to be some manure somewhere.
