  Test your internet connection speed and ping using speedtest.net from the CLI

Speedtest.net using speed-test. These results have been wildly variable. Upload hovers around 5Mbps, sometimes going down to 4Mbps or up to 6Mbps. Download can alternate between 2.5Mbps to 25Mbps in consecutive tests, but mostly around 15Mbps. Latency seems bimodal, switching between 150ms and 250ms.

  iperf3: A TCP, UDP, and SCTP network bandwidth measurement tool

  

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.

  A Smart Ethernet Switch for Earth

  

File transfer using iperf3 over zerotier. I've used Zerotier successfully for years, but sometimes it has trouble establishing connections and picking the right MTU. I couldn't get it to work at all until I lowered the MTU to 1280 (same as Tailscale). This is in spite of the physical network interface using an MTU of 1428. Zerotier has had moments of consistent 10Mbps upload/download, but has generally alternated between 10Mbps or 30Mbps and not working at all.
