Slow Programs

 

 
  • View->System Information: displays graph of cpu usage, hover mouse on graph to determine which process is using cpu.

 

  • Any process (except system idle) using up more than 30% of the cpu, needs investigation. 
    The system process is special, since it exists solely to host operating system threads for memory manager and other subsystems like device drivers. To debug them, double click on the process and switch to the threads page. Vista's new security mode doesn't permit viewing threads, use xperf instead of Process Explorer.

 

Install xperf

  • Open a command prompt and right click to run as administrator
  • Turn on xperf: xperf -on DiagEasy
  • Wait until you see your performance degradation
  • Turn off xperf: xperf -d trace.etl
  • View the performance data: xperf trace.etl

 

 

Install ProcMon

 

  • Once you've determined which process is consuming your cpu, download ProcMon to determine what it's doing.

 

  • Filter->Filter->Process Name->is->Process you found in steps above->Include->Add->Apply

 

  • Toos->view all summary stats.
