Comment on Performance, memory and CPU usage tests of Tailscale, Netbird, Zerotier

Tailscale surprisingly was the fastest, even faster than plain Wireguard, despite being userspace. But it also consumed more memory (245 MB after the iperf3 test!) and CPU.
Do we know if this is a variation due to the test protocol or Tailscale is using wireguard with specific settings to improve, slightly, it’s speed?

Sorry, my autocorrect changed its into it’s.

Another user posted the blog where they discuss their speedup techniques: tailscale.com/blog/more-throughput/
It’s likely that the kernel version can use similar techniques to surpass the performance of the userspace version that tailscale uses, but no one has put in the work to to make the kernel implementation as sophisticated as the userspace one.

That’s nice, I hope the upstream pull request goes through.
