Logging in ReportViewer

Hi

I have a reportviewer in ASP net 4.5 application , but in production environment the report is slow. The report is of  page, and is only data.

But I see the report after 30 seconds. It is not a problem with the database since the database is faster when I connect to SqlServer(1 second).

How can I see execution logs of the reportviewer, not about the database ?

I would like to see something: 

1. Pre-executing 1 seconds
2. Setting values 5 secons.
3. Render 10 seconds
