a consistant 90% or spikes?

What's the output of sysstat -x look like for each node?

Have you opened a support case? issues like this can be hard to troubleshoot in the forums.

hello:

Use "qos statistics volume latency show" to determine if the latency is high. If the latency is not high, it is normal for the CPU usage to be high. ONTAP will use the spare background CPU cycles to complete as many background tasks as possible. The following article can help you troubleshoot quickly. I hope it can be of help to you.
