...Disabled profiler will not affect your application execution in any way. You can leave it in your Release build and enable it at run-time at any moment during the application launch to see what is happening at the moment. Also, the library can capture the system's context switch events between threads. Context switch information includes duration, target thread ID, thread owner process ID, and thread owner process name. You can see the results of measuring in a simple GUI application which provides full statistics and renders a beautiful time-line.
