These numbers don’t make sense to me, even allowing for the fact that throughput numbers are useless without knowing the speed of the server, and the speed of the client internet connection.
But If @simonli can get 156/171, basically maxing out the OpenVPN server, and max out a 500/500 connection with Wireguard, I don’t follow how @emmgr23 can only get 48/38 with OpenVPN on a server that seems to support 166/79 with wireguard. It seems to me he ought to be getting 160/80ish at least.
