Results wrong: download speed 10x high

[robbat2]

There's a performance bug somewhere: this is reading my download speed as 10x too high compared to speedtest-cli

Are you using the cli version or the slim version?

[robbat2]

This was the docker.io/heathcliff26/speedtest-exporter container, using go-native implementation, not the binary.

I switched to ghcr.io/miguelndecarvalho/speedtest-exporter for now, it's good enough

[heathcliff26]

If it works for you, that is fine. Alternatively you could also use the cli tag, that also call speedtest-cli under the hood, same as miguelndecarvalho/speedtest-exporter

This seems to have been a bug in the go-speedtest library i use. It has been fixed upstream and the dependency is also update here, so i'm closing the issue.
