Re: [Bloat] when does the CoDel part of fq_codel help in the real world?

Well, I'm concerned about the delay experienced by people when they surf the web... flow completion time, which relates not only to the delay of packets as they are sent from A to B, but also the utilization.

Cheers,
Michael

My personal opinion is that most people would be better off with 80% of their available bandwidth being in use without any noticable buffer induced delay, as opposed to the transport protocol doing its damndest to fill up the link to 100% and sometimes failing and inducing delay instead.
