Its good that they are running the latency test also during the load test, but from what it looks like, they seem to be running the latency test to the same server as the load test. I think a more realistic test is to run the load test to one server and the latency test to a different server. That's a more realistic use case...

But, just from the code, I know ICMP ping in many cases has a different traffic-class and thus implicitly gets quite a different treatment than real traffic. However, Ookla uses TCP (port 8080) to probe the latency in their app. Christoph > On May 12, 2022, at 12:44 PM, Kathleen Nichols <[email protected]> wrote: > > a ping by any other name... > > Has anyone ever done a rigorous study to see how well ping delays correspond > to the delay that information-carrying packets experience? > > On 5/12/22 10:15 AM, Christoph Paasch via Bloat wrote: >> Ookla's measure of "loaded latency": >> https://urldefense.com/v3/__https://www.ookla.com/articles/introducin >> g-loaded-latency__;!!CQl3mcHX2A!DHnGDBw2sqsRwHiidAQUOhjXEavZmBOtJKb_IzPhxMm2vqUPyRC2pkVnScJId_KdaNVLsOS7sD0E8QRQ0m8B7LqBavY$ >> >> <https://urldefense.com/v3/__https://www.ookla.com/articles/introducing-loaded-latency__;!!CQl3mcHX2A!DHnGDBw2sqsRwHiidAQUOhjXEavZmBOtJKb_IzPhxMm2vqUPyRC2pkVnScJId_KdaNVLsOS7sD0E8QRQ0m8B7LqBavY$ >> > This will hopefully be a shift in how operators approach the bufferbloat >> problem. >> Christoph >> _______________________________________________ >> Bloat mailing list >> [email protected] >> https://urldefense.com/v3/__https://lists.bufferbloat.net/listinfo/bl >> oat__;!!CQl3mcHX2A!DHnGDBw2sqsRwHiidAQUOhjXEavZmBOtJKb_IzPhxMm2vqUPyR >> C2pkVnScJId_KdaNVLsOS7sD0E8QRQ0m8BllXPjdw$ > > _______________________________________________ > Bloat mailing list > [email protected] > https://urldefense.com/v3/__https://lists.bufferbloat.net/listinfo/blo > at__;!!CQl3mcHX2A!DHnGDBw2sqsRwHiidAQUOhjXEavZmBOtJKb_IzPhxMm2vqUPyRC2 > pkVnScJId_KdaNVLsOS7sD0E8QRQ0m8BllXPjdw$ _______________________________________________ Bloat mailing list [email protected] https://urldefense.com/v3/__https://lists.bufferbloat.net/listinfo/bloat__;!!CQl3mcHX2A!DHnGDBw2sqsRwHiidAQUOhjXEavZmBOtJKb_IzPhxMm2vqUPyRC2pkVnScJId_KdaNVLsOS7sD0E8QRQ0m8BllXPjdw$ _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
