ExecuteRequestHandler delay


We are using your tool for our .net WebAPI project, and we have 2 problems about our trace details.
First one is there is a huge delay on ExecuteRequestHandler. We can see some details which we put [Trace] attribute. But generally we can’t find what is the reason of the delay.
Second one is Application code(in …) lines. We can’t find out the inner details of methods.

Any help from you will be really appreciated.
