[Script request]: iperf3

Description

iPerf3 is a lightweight and widely-used network testing utility that measures bandwidth between two systems, making it ideal for diagnosing local network performance or testing throughput between remote machines across the internet.

Since there’s already a script for MySpeed—which is great for checking ISP speed—iperf3 would nicely complement it by focusing on direct network performance between systems you control. This can help pinpoint issues beyond just the WAN connection.

Due Diligence

• I have searched existing scripts and found no duplicates.
• I have searched existing discussions and found no duplicate requests.

Can't you just simply apt install iperf3 on the systems you control? I don't see the need for a standalone LXC.

[klamouri]

Yes, you’re absolutely right that I could just apt install iperf3 on any system I control. But I think there may be a slight misunderstanding—I’m referring specifically to hosting an iperf3 server, not just running the client for occasional tests.

In my case, I’ve set it up on an LXC so I can keep the iperf3 server always running. This lets me:

• Test LAN bandwidth between other devices and my Proxmox server to verify I’m getting full 10Gb performance.
• Run remote tests while I’m away from home to measure how well my external connection performs all the way to my server.

I thought it would be a natural addition to the collection of small utility containers already present in the script library.

That said, is the concern more about adding this kind of LXC container to the repo in general, or just whether it’s worth creating in the first place? I’d be happy to contribute it myself—just wondering if there would be openness to merging it if I submit a PR.

In my opinion (but I don't approve scripts), if there was some kind of web-based UI that can be put on top of iperf, then it would be worthwhile.

I see this request as akin to saying there should be an SSH LXC; like, no - but if there's an open-source, self-hosted webapp that uses SSH (something like NexTerm? Then yes, because that adds something.
