Microsoft: Don't Use Iperf3 on Windows
Just some clarification: IPerf 2 is different from the iperf3 found at https://github.com/esnet/iperf Each can be used to measure network performance, however, they DO NOT interoperate. They are completely independent implementations with different strengths, different options, and different capabilities. Both are under active development.
The current release of iperf 2 is 2.2.0 but 2.2.1 with bug fixes will be out soon.

Speed testing Visible with a modem
File transfer using iperf3 over Tailscale. I noticed that the bandwidth to my home computer (on a 500/500 fiber connection) was higher than with speedtest.net. For the first few days I was getting downloads and uploads of 28Mbps (+/- std dev of 6Mbps) and 150ms latency (+/- 35ms). After somewhere around 100GB total transfer (maybe half of that over Tailscale), it is now downloading and uploading at 10Mbps (+/- 1Mbps). I have not seen a similar throttling in the speedtest.net results, which makes me wonder if it is being throttled by Tailscale. This shouldn't be the case, because Tailscale should generally be able to establish a direct connection, but this isn't guaranteed. So I may have hit an edge case.

Any speed test tool to run on the router to test local speeds?
For a website, there's OpenSpeedTest. I haven't seen this integrated into openwrt (eg. opkg) but it's probably what you're looking for if you're tech savvy.

Ookla speedtest not gigabit speeds but router shows gigabit
Hmm I get 57 down and 28 up using openspeedtest.com. Maybe all these speed test sites aren't good.

Anyone with a ER8411 able to get more than 1Gbps upload speeds?
Playing around with the ER8411 with 5Gbps internet and I am able to get download speeds of 4.9~5.0Gbps but no matter which site I test with; fast.com, wifiman.com, openspeedtest.com, or speedtest.net I am unable to get beyond 1Gbps upload.

PC client throttles my internet speeds by ~40%
Does it affect traffic that's only inside your LAN as well? I use https://openspeedtest.com for doing local speedtests, in case you need a way to test that.
