[Template only, I am not the container author/maintainer]


Template: https://github.com/kilrah/unraid-docker-templates/raw/main/templates/iperf3.xml

Source container: https://github.com/nerdalert/iperf3

Registry: https://hub.docker.com/r/networkstatic/iperf3


The popular network performance testing tool, running as a service.

Spawns an iperf3 instance with the settings you put in the "Post Arguments" field (switch to Advanced View to see it). By default that will be a server on port 5201, which can be remapped in the template.
Clearing Post Arguments will show the help text in the log and stop.


Performance is comparable to running native, at least on gigabit (top is container, bottom is native).

Since a copy of iperf3 is now built-in to unraid this isn't really useful anymore... Just do iperf3 -s -D in Unraid's terminal and you'll have a server running in the background at any time. You can e.g. set up a user script that runs at array start to start it, and if you want multiple you can start several with different ports.

Does anyone know why iperf would resolve to the IPv6 address when using DNS (despite IPV4 Only set). Performance is fine through IP. When it grabs the DNS, it's a fraction of the speed. I don't think that's impacting performance, but curious if anyone has seen this. My hope is that it's an obvious answer for a newbie.




I am pretty sure that ZeroTier is grabbing the address for a virtual interface, however, I can't figure out how to disable it (tried enabling IP4 +IP6, then looking to uncheck something, but nothing is there). Assume it's a config file that needs to be updated.
