If the current values (or current_utilization in AIQUM) exceed the optimal point values (or peak_performance in AIQUM) it is expected to see potentially high increases in resource latency which could translate to increases in protocol/client data latency. The optimal point of ops derived from the latency/utilzation curve for the given interval (daily, hourly, etc).
