Thanks for your quick reply.

I understand that the router has limited CPU and it is already doing pretty well. But, to be honest, if I knew this limitation probably I wouldn’t buy it. It’s a nice piece of hw, I love it, but it doesn’t fit my needs. Don’t you think that it would be better to specify clearly what is the max speed with OpenVPN turned on?

Before returning the router to Amazon: is it possible to turn off VPN encryption? I already edited the ovpn file provided by Astrill adding “cipher none” but then it can’t connect anymore.
