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

Is it possible the others are using the Wireguard kernel module? In that case, a lot of the memory usage will be in kernel/system memory, and just looking at the app’s memory usage won’t be the full story.

Netbird uses kernel Wireguard module, right. Is there a way to measure kernel memory / CPU usage attributed to Wireguard? Zerotier, which has the lowest memory usage, does not use Wireguard at all, they have their own custom protocol and is userspace IIRC.

  Not that I’m aware of, unfortunately.

    I might just compare free output before / during / after iperf3 test. Will do that later today.
