I’ve been on a quest to make the smallest iperf3 container for RouterOS. This constitutes weekend entertainment for me. What can I say; I nerd hard. :nerd_face: What I have so far is here . If you’ve got ~0.2 megs to spare on your router, give it a spin. I’m getting 3.4 Gbit/sec test results to my R…

am I need to use “bridge1” or already existing “bridge” ? like this /interface/veth add address=192.168.88.2/24 gateway=192.168.88.1 name=veth1 /interface bridge port add bridge=bridge interface=veth1 /container add remote-image=tangentsoft/iperf3:latest \ interface=veth1 \ start-on-bo…

it’s working now, thanks [Screenshot at Dec 02 15-37-19.png]

iperf 3.16 is out, with a significant performance jump in multi-stream tests. My RB4011 numbers went from 3.4 Gbit/sec for 4-stream downloads to over 4 Gbit/sec atop OM4 with generic SFP+ modules. IMO, it’s worth recreating your containers to use this version. (And upgrade your clients, too.)

surprised to see CPU util jump to ~ 25% as iperf3 is doing its thing. If you monitor the client side on your PC, you will find that iperf3 takes CPU resources to do its thing there, too. Why would a smallish ARM CPU be different? You want my opinion, you should be thanking MikroTik it isn’t pe…

You would have had to go out of your way to get anything else, assuming you’re using the latest version of the Makefile, which hard-codes the “3.16” release version string. You can double-check it with a command like “docker run -it --rm tangentsoft/iperf3 --version”. Ah, I missed the –branch …

native iperf3 on rpi4 is ~ 4% CPU usage. And you’re getting a lower speed test result on the Pi, aren’t you? CPU usage is a function of throughput. It takes more grunt to push 10G than 1G.

The rpi4 is 1Gbps capable, so I get around 945Mbps to the iperf server in my RB5009 :sunglasses: The highest speed I can test is 1.5G from RB5009 to my Bell modem, the Mk is connected using the 2.5G port, but I can’t make that test as the Fibe modem doesn’t obviously run iperf.

Here’s a screenshot of the RouterOS profile I get while doing a ~4.1 Gbit/sec test over OM4 to an RB4011 with iperf3 3.16 set for 4 parallel threads: [ss.jpg] That’s a pretty direct scaling factor: four times the bandwidth for four times the CPU power.

Very very good Give the latest alpine 3.18 iperf3 a test: https://hub.docker.com/r/elicro/iperf3-server The next is a test from a windows machine over a connection between HAP ax2 to an HAP ac2 which hosts the iperf3-server. Seems pretty decent to me. PS C:\Users\Administrator\Software\i…

FWIW, they do offer /container/run in 7.21:
