title: Why do we need debug information during profiling using Vtune?
body: <p>When we profile an application using VTune, I understand that the application should be compiled in Release mode, so that it has only relevant code and no additional code for debugging or something else. But <a href="http://software.intel.com/en-us/node/471878#USER_DLL" rel="nofollow">following this article</a>, I notice that it mentions to collect debug information. Why this debug information is required? Will it not make inaccuracy in the timing report due to overhead of these debug information?       </p>
