Hi Brennen – on #3, do you mean that (if we look for example at https://www.speedtest.net/result/i/5112435305) that 419ms is the mean/average? And when we see a result page like https://www.speedtest.net/result/i/5112435305 how do we expand/see detailed results that have low & high*? And is high max or p99/p98/p95? And will this be added to the MacOS client soon? Thanks for Ookla doing this BTW! Jason * If that is not possible in the current version, please suggest it as a feature request for your team’s next code sprint.

Loaded latency is simply an extension of the latency stage - same methodology and medium 2. We use a "warmed up" TCP connection for latency 3. We use the interquartile mean for the "displayed value" Awesome seeing those numbers in the wild and looking forward to bringing more awareness to this issue.

I hope to learn more about their calculations in the coming weeks. I do keep hoping we can get more updated flent data over longer intervals than 20s. With starlink changing their allocation scheme every 15s, what number do you pick? And like I said, some packet caps of this app would be good, too.

I'm interested in calibrating the results of that vs a vs flent benchmarks verses starlink. Can someone here give this a shot? More details here: https://www.ookla.com/articles/introducing-loaded-latency IDEALLY, this would be over wifi -> starlink , with a packet capture in the middle. But I'd settle for a few test results from starlink folk of this new app, first. -- FQ World Domination pending: https://blog.cerowrt.org/post/state_of_fq_codel/ Dave Täht CEO, TekLibre, LLC _______________________________________________ Starlink mailing list Starlink@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/starlink -- FQ World Domination pending: https://blog.cerowrt.org/post/state_of_fq_codel/ Dave Täht CEO, TekLibre, LLC ________________________________ This email, its contents and attachments contain information from Ziff Davis, Inc. and/or its affiliates which may be privileged, confidential or otherwise protected from disclosure.
