Ironically scp/sftp caused me more bandwidth headaches than wireguard/openvpn. I frequently experienced cases where scp/sftp would get 10% or even less of the transfer speed compared to a plain http(s) connection. Maybe it was due to packet loss, buffer size, or qos/throttling, but I wasn't able to figure out a definitive solution.
