@hellomiakoda It has some overhead, but unless something extra weird is going on it shouldn’t be worse than using https. Wireguard/Tailscale _might_ need to reestablish a TCP connection if you change networks…but I’d bet in a lot of cases it would transition between network routes and keep the connection open. I’d be curious what result you get if you SSH into your phone and turn on and off the cell/wifi while tailing a file.
