Odroid-HC1 strange networkspeed (slow)

Frepke · 13. August 2019

Hello,

I've an Odroid-HC1 running on OMV4 with the latest updates and connected direct to the routers LAN-port.
My internetconnection is 1000Mbit/s up/down.

When I test my internet network speed with iperf3 and a public server, the speed is good enough:

But when I test it with speedtest-cli the results are bad:

When I try a testfile in SABNzbd, I only get 6MB/s.

Is there a way to improve my network/download speed?

TIA.,
