Enabling the iowait
time statistic to be frequently high indicates that the CPU is overutilized due to processing too many operations simultaneously.

True
The iowait
time statistic actually represents the time the CPU is waiting for I/O operations to complete. It is not an indicator that the CPU is processing too many operations but rather that it is idle and waiting, which can imply I/O subsystem issues rather than CPU overutilization. High CPU utilization is better indicated by statistics like user and system time ratios.
