How to run iperf3 on Synology NAS using SSH

I prefer this method to the GUI docker method because:

• It’s much more reproducible in practice
• It involves fewer steps
• It uses --net=host and therefore doesn’t involve additional routing, bridging or forwarding of packets which might impact performance

Login to the Synology NAS over SSH using a user with admin privileges, then sudo su.

For using iperf3 as a serve, use

docker run  -it --rm --name=iperf3-server --net=host networkstatic/iperf3 -s

For using iperf3 as a client, use

docker run  -it --rm --name=iperf3-client --net=host networkstatic/iperf3 -c 10.1.2.3
