Hi,
Please refer to this setup and give it a try:
The maximum speed of the 10G network port of the ORIN-32GB module can only reach 6.5G using iperf3 - #4 by DaneLLL
We try it on Jetpack 5.1.1 with the commands being executed:
$ sudo nvpmodel -m 0
$ sudo jetson_clocks
It should be same result on 5.1.2.
