How to: Profile with the Performance Wizard and Profiler Defaults
The Visual Studio Profiling Tools features and options enable you to completely control a profiling session. But in many cases, all that you need to discover performance issues in your project is to use the Performance Wizard to configure the session, the default settings of the Performance Explorer and Data Collection Control windows for data collection, and the standard Profiling Tools report views of the data.
This topic describes how to quickly profile a Windows client application by using the Performance Wizard and Profiling Tools default settings. The following procedures are described:
How to use the Performance Wizard to configure a performance session for a project.
How to collect performance data for an application, including how to insert marks in the profiling data file to assist in data analysis.
How to view and filter the performance data in the Visual Studio IDE.
How to use the Hot Path filter in the Call Tree view to find the functions in which your application spends the most time.
Because profiling can be complex, following the procedures in this topic will not guarantee that you identify a critical performance issue in your application. The topic is designed as an introduction to the Visual Studio Profiling Tools.
