Is the kernel module how they claim the 5x performance over tailscale? I haven't really done any real tailscale performance metrics but can't see how else they can claim this (unless there is infrastructure performance differences).
I remember reading a blog post on tailscacles' website about it and how they are pushing their changes upstream (wg kernel and official wg go user space implementation).
Can't find the post now though.
The numbers Netmaker posted likely come from: https://medium.com/netmaker/battle-of-the-vpns-which-one-is-...
Note that a spreadsheet with raw data and command used (which is all `iperf3 -c <IP>`) is here: https://docs.google.com/spreadsheets/d/1Qy27zEERSqisdV1u-YUc...
While it's a good idea to be skeptical of a company tooting it's own horn, there does (or has) seemed to be a consistent performance advantage that is beneficial to those who aren't paid for or like being a network admin beyond setting a proper MTU: https://techoverflow.net/2022/08/19/iperf-benchmark-of-zerot...
However in light of https://tailscale.com/blog/more-throughput/ (thanks to FabHK for bringing this to my attention) testing should probably be redone.
