Increasing Website Performance - ASP.NET

I am working on a .NET website and trying to speed up the loading time. My problem is that even for the Home Page(not loading any object data) it takes significant amount of time to load the homepage. I have put loggers everywhere to find out whats causing the problem and this is what I have so far:

2016-06-01 12:10:04,217 [5] INFO  - BaseController/SetPrincipal(): Started - 01/06/2016 12:10:04 PM

I'm aware that I have to use min files for the bundles and tweak the SetPrincipal method to speed it up. But my question is that after the index calls View() to display the layout, it takes approximately 1.5 seconds to load the layout. How can I find out whats causing this delay? Any help is appreciate! Thanks :)

Update: I guess I will mark usr's solution as the answer as thats the only solution recommended so far but I'd really appreciate if you guys can recommend anything else

Profile the code. The hot code will be obvious.

Or, pause the debugger 10 times under load to see where it stops most. That's the code that consumes most time.

This technique is called the poor man's profiler by the way. I often prefer it to an actual profiler because I can inspect the app state in the debugger. Pro tip: Run parallel load and use the parallel stacks window. That way you get a sample of N threads presented as a tree!
