CPU Utilization Is Wrong (2017)
I love Brendan&#x27;s article about load averages but I feel like this is missing the mark.<p>A core, or an execution unit stalling within a core, still count as busy.  I.e. the CPU can&#x27;t process something else.  The utilization metric is correct.  The question of whether a CPU be used more efficiently is in the domain of optimization.  It might be executing NOPs and not stalling.  It could be using an O(N^3) algorithm instead of O(N).
