Question

I seen on the page http://ablogaboutcode.com/2012/01/12/a-simple-rails-boot-time-improvement/ than the rails boot time is long because Rails load all gems at start. I checked it on my project and it’s true, the loading of gems take 20 seconds on 30.

I try to add require false at the end of a lot of gems in my Gemfile and I gain 3/4 seconds. Not a huge improvement.

I try the load time with this command :

time bundle exec rake environment

So, my question is : Is there something, like spork or something else, to preload all gems and decrease the boot time?

Thanks!
