Zeus taking minutes to run tests, Rspec taking seconds?

Some of the individual tests are lightning fast with Zeus, and others are pretty dang slow.

If I do:

time rspec spec/

The result is:

Finished in 35.36 seconds
220 examples, 0 failures

real    0m59.018s
user    0m43.723s
sys 0m2.495s

But if I use Zeus:

time zeus rspec spec/

The result is:

Finished in 7 minutes 9 seconds
220 examples, 0 failures

real    7m13.053s
user    0m0.279s
sys 0m0.047s

What's up with this? Below is my spec_helper file:

    require 'selenium-webdriver'
    require 'sunspot/rails/spec_helper'
    require 'timecop'
    # require 'webmock/rspec'
    #uncomment the following line to use spork with the debugger
    #require 'spork/ext/ruby-debug'

    def spork?
      defined?(Spork) && Spork.using_spork?
    end

    def setup_environment
      # This file is copied to spec/ when you run 'rails generate rspec:install'
      ENV["RAILS_ENV"] ||= 'test'

      if spork?
        ENV['DRB'] = 'true'
        Spork.trap_method(Rails::Application::RoutesReloader, :reload!)
      end
