I wonder if the post's focus on Linux/Android is just because that's where they started, or because they're leveraging techniques that are only possible on Linux/Android?
(Tailscale cofounder) Yes, that’s most of it. Most packet-level optimizations are necessarily platform specific and this post was mostly about the linux dataplane.
That said, the architectural multiqueue improvements and memory optimizations are useful starting points to build on for every platform.
