Hello,
for i in `seq 1 1000` ; do ip link add dev wg${i} type wireguard ; done
=> kernel thread kworker  is 50% cpu time   , with 5000 interface ,
100% cpu time

for i in `seq 1 1000` ; do ip link add dev ifb${i} type ifb ; done
          ( ifb or dummy .. )
=> kernel thread kworker is < 1%

Is it normal behavior ?
 Version : WireGuard 0.0.20170409
  kernel : 4.9.23
