~85.5% of native code when profiling with Jet Brain's dotTrace?

Whenever I do a session (both samplig and timeline), it says like up to 70-80 percent of entire exuction is occupied by native code. It seems kind of suspicious, not quite sure whether I got a buggy environment (because due to objective restricitions I am working on a damn Windows 7) or it's actually fine?

Solution

  • It is a normal situation in case of profiling a web application hosted on IIS as IIS is a native application itself. So if all of your app's methods are presented in a snaphot then you have nothing to worry about.

    See this page for details: https://www.jetbrains.com/help/profiler/Profile_ASP_Web_Site.html
