And thank you for doing so! When reading it, it strikes me, that you don't directly tell them what to do; e.g. add a latency test during upload and download. You say so indirectly, and points to a website with an implemented solution. My point is, it requires work from their side, to lookup a solution and understand it. I want something even simpler like add test that: "measures latency while measuring the speed" (your own formulation from betterspeedtest.sh) The reason, this email and this requirement have to be passed on from person reading the mail, to management, to the developers in the company. =20 > > "Dear speedtest.net/speedof.me please add a latency test, that measures > > latency during the upload and download test-runs." > >=20 > > That will be the first baby step, don't make it too complicated for > > them, afterwards we can start explaining if we want min/max or 98th > > percentile. > >=20 > > They already have a ping facility, which the only run _before_ starting > > the test run.
