Need to speed up automapper…It takes 32 seconds to do 113 objects

Question

Hi I have some major problems with auto mapper and it being slow. I am not sure how to speed it up.

I am using nhibernate,fluent nhibernate and asp.net mvc 3.0

A good tip is to optimize the configuration of AutoMapper, use Ignore for the properties of the ViewModels, and make the method call to validate the mappings "Mapper.AssertConfigurationIsValid()".

Mapper.Initialize(cfg =>
        {
            cfg.ValidateInlineMaps = true;
            cfg.AllowNullCollections = false;
            cfg.AllowNullDestinationValues = true;                
            cfg.DisableConstructorMapping(); // <= In the case of my project, I do not use builders, I had a performance gain.
            cfg.AddProfile();
            cfg.AddProfile();
        });
Mapper.AssertConfigurationIsValid();
