NHibernateSession.Init slow (S#arp 2.0.4, ASP.NET MVC 4.0, VS2012 RC)

I'm looking to uplift our project from S#arp 1.0, ASP.NET MVC 1.0, etc.  I decided to start a test project from scratch with the latest toolset.  I am able to get the site running and have two basic objects (only the Id field) mapped from our database.  However, when I try to run the website from within VS2012 RC, there is a very long delay before the homepage is displayed.

I put in very crude debugging lines into Global.asax.cs just to get a very quick idea of where the time is being spent.  Here's the console log:

--Snip lots of dll lines loading--
8/6/2012 8:36:40 AM - Start Application_Start()
8/6/2012 8:36:41 AM - Start InitializeServiceLocator()
8/6/2012 8:36:41 AM - End InitializeServiceLocator()
--More DLLs loading --
8/6/2012 8:36:42 AM - End Application_Start()
8/6/2012 8:36:42 AM - Start Init
8/6/2012 8:36:42 AM - End Init
8/6/2012 8:36:42 AM - Start InitialiseNHibernateSessions()
8/6/2012 8:36:42 AM - Start AutoPersistenceModelGenerator.Generate()
8/6/2012 8:36:42 AM - End AutoPersistenceModelGenerator.Generate()
8/6/2012 8:38:55 AM - End InitialiseNHibernateSessions()
8/6/2012 8:38:57 AM - Start Init
8/6/2012 8:38:57 AM - Start Init
8/6/2012 8:38:57 AM - End Init
8/6/2012 8:38:57 AM - End Init

There is a 2+ minute delay that comes from the call to NHibernateSession.Init(...) which is within InitialiseNHibernateSessions().  I see some NHibernate discussion from 2010 regarding Fluent NHibernate and XML serialization.(http://nhforge.org/blogs/nhibernate/archive/2009/03/13/an-improvement-on-sessionfactory-initialization.aspx), but I'm not sure this is the same thing or not.

Is anyone else seeing a delay similar to mine?  I can understand that the initialization will take sometime, but the old project only takes 15 - 20 seconds with many, many more and complex objects.  Do I have a web.config setting wrong?  Is there something in the Infrastructure project I should do differently?

Thanks

Joe

That is an insanely long time, it definitely shouldn't take that long.
What does your AutoPersistanceModelGenerator code look like? Do you
have any extra conventions configured?

I just tried it now with a solution that has 8 entities mapped, and
from hitting F5 to viewing the page it takes < 5secs
