That is quite weird, any router above 80% would probably slow down your network traffic. Did you add cpu service or discover it?
where is the problem exactly? you probably have two cores, that’s why you have over 100
but it says rb-500 ROS 2.9.50..
Dual core RB532? that’s hot! 
Board is RB133.
Real CPU load about 10%.
This is Dude 3.0 bug.
I will upgrade to 3.2 in few days and see what hapens.
It is more fun than problem.
Isn`t it miracle to run CPU at 150% at least for a while 
You see, i run it on 150% for days.
LMAO !!!
