Spork initializing rails each time and running slowly - ruby-on-rails

Question

I need help figuring out why my rspec tests are running slowly.
I am running spork, guard, and rspec. However, it appears that spork is re-initializing rails each time. I am having a difficult time figuring out how to debug this issue. I suspect some gem I am using is causing this but have no proof.
The reason I think it is reloading is:
It takes the same amount of time to run inside of spork or outside
I get this warning (related to the SOLR gem) that I get when I run
rails server

# need to restart spork for it take effect.
# This file is copied to spec/ when you run 'rails generate rspec:install'

# Remove this line if you're not using ActiveRecord or ActiveRecord fixtures

You can profile spork and use the results to require stuff in the prefork block
http://www.opinionatedprogrammer.com/2011/02/profiling-spork-for-faster-start-up-time/
There is also an issue with Devise and possibly other gems calling reload, these methods can be trapped by adding the following to your spec_helper prefork block:
...
ENV["RAILS_ENV"] ||= 'test'
# For Devise
require "rails/application"
Spork.trap_method(Rails::Application, :reload_routes!)
Spork.trap_method(Rails::Application::RoutesReloader, :reload!)
...
