I went to bed early yesterday, and woke up to slashdot.

despite most of the debian derivatives adopting fq_codel, debian
hasn't due to confusion at which team should step up.
The issue got raised again for the next release, and code rebased:

h is I think the test needs to run longer at these speeds.
Another another kvetch is they factor in baseline latency to determine
if the link is suitable for gaming or not.

It really bothers me that our mailing lists are not indexed. Perhaps
this could help? Anyone tried it?

A nice comparison of BBR vs Codel vs FIFO vs their cross-layer
solution. (they used irtt!)
I am always puzzled as to why folk don't benchmark fq-codel (or
something like BQL)
in scenarios like these. Are the headers not available in the RAN?
(forgive me for forgetting)
Anyway, their "vanilla" sce

I don't know when this came out, but I missed it. Certainly I hate
running out of cpu as much as anybody, and wish we were shedding load
by measuring total time from ingress to egress, or...

What's the real barrier to doing this nowadays? We use signal in this
way, sort of:

OK, I finally bit the bullet and started editing wikipedia for the
first time, seriously. That said, i have very little patience for it,
especially cite hunting. It's taken me, what? 8 years to attempt this.
There's an awful lot on wikipedia that needs improvement elsewhere
also.
