currently i'm using a site-2-site openvpn setup. The routers en/decrypt all traffic that goes from one net to another. One of them is the Openvpn server. This works but performance is not as good as possible. I think the limiting factor is the cpu power of the router.

Would it be better if i use client-to-client connections and access the fileserver in the one net from a pc in the other, because the openvpn-server does not have to decrypt the (whole) packets?
