How to get my guard/rspec test to run faster

Question

I am running the following gems in a rails 3.1 app ontop of ruby 1.9.2:

group :test, :development do
gem 'turn', '<0.8.3'
gem 'rspec-rails'
gem 'capybara'
gem 'guard-rspec'
gem 'minitest'
gem 'ruby_gntp'
gem "win32console", "~> 1.3.0"
end

I have only initialized guard and rspec by running the

rails g integration_test MyApp

command.

so, I have only the one sample test that is generated by the command. it looks like this:

 require 'spec_helper'

describe "Tasks" do
  describe "GET /tasks" do
    it "works! (now write some real specs)" do
      # Run the generator again with the --webrat flag if you want to use webrat methods/matchers
      get tasks_index_path
      response.status.should be(200)
    end
  end
end

for some reason, when i run guard, it takes guard and rspec between 3.5 and 5 seconds just fail this on little test. On the tuts I've seen, their machine runs this exact test in about .0159 seconds on a Mac. What can I do to increase the performance of these test?

I am running this on a Windows 7 machine.

Has anyone dealt with this situation?
