Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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.
