My freenas tested with iperf3 and I encountered uploads of up to 10G, but when iperf3 added the parameter -R, it was only about 5G when downloading. In the same network environment, my upload and download between win10 and win10 can normally reach 10g. The network card is inter x520-da2. Make sure it is plugged into pcie3.0 x4. Thank you for your help!

Try iperf2
iperf. I found that iperf3 gave me odd results on my hardware, particularly on the 40G linkes.But iperf2 doesn't seem to support 10g. My environment is 10g. Thank you for your help!

The iperf v2.0.11 program supplied with FreeNAS supports 10G:
