 # THANKS EVERYONE FOR YOUR BELOVED BENCHMARKS.
 # THIS PATCH IS NOW IN RAILS:
 #
 # https://github.com/rails/rails/commit/885a599303585b796da7a0a1c3ccd0bc5c642134 

 # Please add the following lines after Bundler.require
 # and before "class Application < Rails::Application"
 # in your config/application.rb
 #
 # Notice this is just an experiment, don't leave those
 # lines there after the experiment. Then please benchmark
 # your app boot time in development before and after adding
 # those lines. A simple benchmark is:
 #
 #   time script/rails runner "MODEL"
 #
 # Where MODEL is a model available in your app. Also,
 # please run the command above at least three times to
 # ensure we don't have fake samples. :)
 #
 # Please post the results in the comments below of the
 # benchmarks before and after adding the code. <3
 #
 # This patch should work on Rails 3.0, 3.1 and master.
 #
 # Extra: if you could run your app in development and
 # production (in your machine!!) with this patch on
 # for a couple minutes and report any errors, you will
 # win extra <3 <3 <3.
