What is CPU Profiling? 

  • CPU profiling provides information about where an application is spending most of its time 
    • Execution performance profiling 
  • When is CPU profiling needed or beneficial? 
    • Poor application throughput measured against a predetermined target 
    • Saturated cpu utilization 
    • High sys or kernel cpu utilization
