How to do site-to-site traffic over Tailscale / WG encryption? From preliminary testing, it seems have difficulty to saturate a 10Gbps connection while plain HTTP (nginx) traffic does that fine. Of course it should vary from CPU to CPU, but any tips how to improve that? Ideally I would love to go over with encrypted traffic, although everything is public, just one less thing need to be careful (in case future need to transport some non-public data over).
You'd need to analyze what's bottlenecking when you're doing that.
Even a cursory look at htop on both ends while you're trying to saturate that link would be informative.
