Help Test MiniRacer.md

MiniRacer https://github.com/discourse/mini_racer is ready for testing.

Can you help out measuring how it improves performance for rake assets:precompile in your app?

Run:

rm -fr public/assets
RAILS_ENV=production time bundle exec rake assets:precompile

Edit Gemfile. Remove therubyracer, add:

gem 'execjs', github: 'rails/execjs'
gem 'mini_racer'

bundle install
Run:

rm -fr public/assets
RAILS_ENV=production time bundle exec rake assets:precompile

Are you guys deleting the sprockets cache (tmp/assets) between runs? I got several times speed up at first too but then after doing that the speed up was reduced to 25% (still good, but not as unbelievable as I first thought).

I've been using assets:clobber

Cleared caches and made sure spring wasn't running. Results:

therubyracer: 3m50s user
