I’ve found that _usually_ I can set cake’s bandwidth limits to 90-95% of the advertised bandwidth, and everything “just works”. So long as you’re routinely able to achieve the bandwidth, it tends to work. I’ve found in my testing over the years (I’ve been a user of fq_codel since 2013) that

Thanks for the detail. It makes sense but it kind of feels like in some (maybe many) cases the router could know the internet link performance. Particularly home router-modems often monitor this already. Maybe that's just not exposed in any standardised way? I'm guessing if I was into openwrt I

Hi, On the website it says the following: *CoDel is a novel “no knobs”, “just works”, “handles variable bandwidth and RTT”, and simple AQM algorithm.* - *It is parameterless — no knobs are required for operators, users, or implementers to adjust.* - *It treats good queue and bad queue
