Hi all,
I am using wireguard for a while now along with a wifi connection. I noticed, after switching to an ethernet connection, that the cpu load is constantly at 20% and the fan noise on my laptop is increasing remarkably. If i disable wireguard, the cpu load goes back to normal. Pf does not play a role, because the second thing i did was to disable it without any effects. Also,
My
Does anyone know what could cause the increased cpu load? Where could i debug further?

tcpdump the wireguard interface doesn't reveal any unusual outgoing/incoming traffic.My
