Orange Pi 3B(RK3566) armbian network speed issue

[dmdelaos]

When comparing network speeds on the orange pi 3b 8gb model using armbian (Jammy Gnome 6.8.2) and Opios (aarch64-xfce-opi3b-23.08.1-linux5.10.160), there seems to be an issue with uploads on armbian.

 

Using iperf3 for testing, the results were as follows:

 

For orange pi os (arch):

From other device (server) to orange pi 3b (client): 112mb/s

From orange pi 3b (server) to other device (client): 112mb/s

 

For armbian:

From other device (server) to orange pi 3b (client): 112mb/s

From orange pi 3b (server) to other device (client): 42mb/s

 

I would like to know the cause of this problem and how to solve it.
