CPU Usage: What is n/a attributed to? RRS feed

  • Question

  • WPA Windows Performance Analyzer

    When looking at sampled CPU usage for a process, sometimes a considerable amount of time for the process is consumed by "n/a", adjacent to "[Root]" in the Flame Graph and Data Table views.

    What is this?  In some cases, I have seen up to 25% of the CPU time spent here.
