wrong measurements?

[MizarCs]

It's about a couple of months that my internet-pi is measuring 258Mb/s despite https://www.speedtest.net tells me 786Mb/s: this is a huge difference and I don't know why it's happening.
Any advice?
Is there a "Docker networking" issue ongoing?
My Rpi 4 is connected straight to the router connected via WAN port to the the fiber coupler.
TIA

Hi @MizarCs,

to really investigate the problem, you should probably go to the speedtest docker frontend on your pi-hole at port 9798 and have a look at the details there.
And based on that, the underlying repo https://github.com/MiguelNdeCarvalho/speedtest-exporter might be a good resource too.

You mentioned Rpi 4, which should do 1 Gbps over the integrated ethernet. So I guess we can exclude potential trouble sources of Ethernet-over-USB dongle or older Raspberry Pi versions, which could introduce a 300 Mbps limit.

If you want to double check the reported speed, you could also test-drive my pull request #475, which runs the speedtest on Cloudflare instead of speedtest.net.
Or if you want to keep it simple, just run my underlying docker image and see what results it gives you: https://github.com/martinbrose/cloudflare-speedtest-exporter

Just a few ideas. Happy to help if you need further guidance.

Cheers

Hi Martin,
sorry for the "delay", I really missed your reply and noticed today the count down to close it in 30 days.
I'm far from home now and I'll be back in few days so I can check what you suggest. I hope to have a feedback for you soon.
Thanks a lot and I'll be in touch hopefully soon.
Regards

well ....
I reinstalled all (disabling pi-hole) and it seams I have the same issue.
I'm currently using a Raspberry Pi 4 with 8GB ram so you got it right

Any other advice is very welcome.
