Point is that iperf itself is using a huge amount of CPU. You can run your
test and launch "top" in another SSH window. In my experience for slow CPUs
during such tests the CPU use may be like 60% iperf.

If your typical scenario is router just forwarding packets between networks
and into WG tunnel, and not providing any network services itself (such as
Samba), testing with iperf launched on the router will not be representative
of real-world usage bottleneck or lack thereof.
