you have a speling error (ECM). :)

side note:

I have to say that wireguard works really well with ecn and non-ecn marked flows
against codel and fq_codel on the bottleneck router.

I'd still rather like it if wireguard focused a bit more on
interleaving multiple flows better
rather than on single stream benchmarks, one day.

In this case, codel is managing things not fq and we could possibly
shave a few ms of induced latency off of it in this particular test series:

vs wireguard (doing it ivp6 over that ipv6)

That said, I've been deploying wireguard widely in replacement of my
old tinc network particularly on machines that were formerly cpu
bottlenecked
and am insanely pleased with it. what's a few extra ms of latency
between friends?
