screen capture of Visual Studio profilers

I am not knowledgable on how to use the Visual Studio profiler at all.
The profile shows that the JavaScript binding to SDL is where most of the time is spent. But this is totally expected. The question is why is Windows 100 times slower overall? The language bindings are exactly the same for all platforms... public JavaScriptCore C API.
