High CPU Usage UDP Remote Port Forwarding

Is it normal to have 95% CPU when using ssf UDP remote port forwarding? Testing the connection with iperf and speeds of 70mbps.

I noticed the same issue on both client and server, but only during about the first minute, then the consumption was pretty low or even zero, while streaming a remote screen.
