I would be so happy if someone independent ( and not necessarily me!) was validating those more private tests, and retaining reference packet captures of the various behaviors observed. Bloat is just one problem among many, that shows up on a speedtest. I have, for example, been working for months, on a very difficult problem occurring on at least one wifi6 chipset... where the block-ack window is being violated, leading to a ton of jitter under certain loads, and a bandwidth reduction, that doesn't show up in summary data.

I have cc'd ippm a few times on these threads, and am on that mailing list. It's pretty moribund compared to around here. I am primarily interested in correct code (be it from a specification, or not), and in looking at packet captures, to validate that it is doing what it says on the tin, and moreover getting more stuff on those tin, that I already know, should be tested for. I agree that someday trying to nail down what latency under load means, would be good to do. I'd settle at the moment, for single flow simultaneous, tcp up, down, ping, and within stream latencies... all plotted on the same chart. > JL > -- This song goes out to all the folk that thought Stadia would work: https://www.linkedin.com/posts/dtaht_the-mushroom-song-activity-6981366665607352320-FXtz Dave Täht CEO, TekLibre, LLC _______________________________________________ LibreQoS mailing list LibreQoS@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/libreqos
