High CPU utilization for AEM environment even with 0 pages in it.

The cloud manger production pipeline fails at performance testing saying that it has CPU utilisation more than 80%. But stage environment has 0 pages in it and it is a brand new environment that was recently provisioned. Why is this happening? Is there a way to troubleshoot this issue to understand what is taking more CPU?

Can you please try downloading thread dumps & analyze if there any "RUNNABLE" & "BLOCKED" threads which is impacting on CPU utilization. also check active scheduler jobs which is taking longer time than expected.

Have you checked the new relic results for the reported execution? Related to how we compute the CPU utilization value. CM always get the MAX CPU between all the instances. We are doing the same for other instance related metrics (memory, network traffic) etc.
