Can you copy&paste the output of powertop? It's not always clear what is being
reported. I'm using PowerTop v2.0, and nowhere does it actually show the power
consumption in Watts for individual resources. In the "Device stats" panel, it
shows relative usage for individual resources, but that is either a percentage
(of what is not clear, the sum of all percentages is much more than 100% on my
laptop anyway), or a number of events per second (for example, ops/s for the
GPU, pkts/s for network interfaces). If there is no traffic on the VPN
interface, PowerTop on my laptop says 0 pkts/s. When connected to the VPN but
otherwise idle, the "Overview" panel shows that tincd has only between 0.3 and
1.0 wakeups/s.
