As these will use different number of= upstream/downstream flows per profile making comparisons between different= profiles harder. I would recommend to get a free dslreports account and us= e the speed test configuration to use a fixed number of flows per direction= (I typically use 16/16, but on slower links often I do not get all 16 goin= g, in that case I retry with a lower number of flows, also set manually). A= fter registration you can also request high resolution buffer bloat measure= ments, which nicely illustrate a link=E2=80=99s behavior under load (but mi= ght not work well on very slow links, so maybe you are already running the = optimum configuration). Thank you. I did so, and here's the latest result: https://www.dslreports.com/speedtest/4524841 It varies greatly. I think that it's due to the nature of the 3g connection= .
