Only the optimizer is working. The CPU utilization is fluctuating. 70% of the time it is in a high range (75 - 95%). 30% of the time it is in a lower range (5 - 10%).
I continued to study the low CPU usage. The load is low if I'm not logged in on the pc (WIN 10 Prof.). I am logged in then the CPU usage increases - see attachment. When I am logged in for a while (10 min) then the cpu usage fluctuate.
