I would like to find out openvpn client performance such as third party vpn provider like surfshark or nordvpn as per download and upload speed. I want to know if this modem supports hardware accelerated crypto. My current modem (asus ac52u)  does not support hw accelerated crypto therefonre my speed cannot exceed 8mbit/sec with using openvpn client on the router. I am looking for a replacement model of asus due to vpn performance
