how to use visual studio profiler

steps to use Visual Studio Profiler:

Note Visual Studio Profiler is available with Visual Studio 2010 Premium and Visual Studio
2010 Ultimate editions.

In Visual Studio, on the Debug menu, click Options And Settings.
2. In the left pane of the Options dialog box, click Debugging, and then click Symbols, and
ensure that the symbol file is loaded for the XppIL folder of the AOS that you want to profile.
(The profiling tools use symbol [.pdb] files to resolve symbolic names such as function names
in program binaries.)
3. On the Analyze menu, click Launch Performance Wizard to create a new performance session.
4. Accept the default setting of CPU Sampling, and point to the AOS that you want to profile, but
don’t start profiling right away.
5. Open Performance Explorer, right-click the top node of your session , and then
click Properties.

6. In the Properties window, navigate to Sampling and decrease the sampling interval either to
100,000 or 1,000,000 to get better results.
7. Prepare the process that you want to profile, and then click Attach/Detach to attach
to the
process (for example, the AOS).
8. When you are done profiling, click Attach/Detach to detach from the AOS.

After you finish profiling, Visual Studio generates a report that helps you understand the
