Performance
As typical of any VPN application, ReadyNAS Remote uses an additional TCP or UDP
header that introduces marginal bandwidth overhead in order to tunnel from the private
network interface. The relative overhead depends on the size of the packet being
transmitted, however, on average, the ReadyNAS Remote overhead is approximately 5%.

Since ReadyNAS Remote is a user space application (as opposed to a kernel application) it
also consumes some CPU resources. All traffic flowing over the virtual network is encrypted
and with a packet-inspected firewall to allow only CIFS/SMB and AFP traffic. The amount of
CPU resources used depends on the data transfer rate.

For example, if using ReadyNAS Remote and transferring data over a 100 Mbps LAN you
may see some measurable CPU usage. The CPU usage may be reduced by not encrypting
the traffic flow.

WARNING!
NETGEAR does not suggest disabling encryption, but it is an
