Available CPU performance capacity is the difference between optimal-point utilization and current utilization. With current utilization at 86 and the optimal point at 72, the capacity is 72 − 86 = −14. The negative value indicates CPU utilization is beyond the optimal performance point. NetApp defines current_utilization as average processor utilization and optimal_point_utilization as the utilization component of the latency/utilization curve.
