Gem is slow to load

[stevecj]

I have been trying to shorten my Rails app startup times, so I benchmarked the gem requirement times using the trick described at http://stackoverflow.com/questions/9505612/slow-loading-time-for-rails-3-2-debug-shows-rails-loading-twice.

I found dynamic_form to be the slowest-loading gem next to Devise (which notoriously slow-loading).

Any idea why the loading of dynamic_form is so slow and how to speed it up?
