Speed Test is showing incorrect values after a period of time/executions

[Gardosen]

Hello,

i am using this docker compose setup now since around 1 week.
what i noticed, and i can not figure out why this happens, is that the test results are matching my manual tests on the start of the containers.

but at some point, the docker tests are at around 100mbit/s, which is not matching my manual test in that moment then. (i use ookla for the manual test and downloading test files from my own dedicated server at hetzner in germany) both gives me a result of around 170mbit/s.

when i delete the entire container setup, and set it up from scratch, also the docker containers show this value again.

is there anything someone here has as an idea what goes wrong with my setup?

Kind regards
Gardosen
