title: Rails 3 initializes extremely slow on Ruby 1.9.2
body: <p>I'm using RVM for managing environment, installed Ruby 1.9.2.p136  (i think its latest release.) and Rails 3, created gemsets and run bundler. everything working good so far 
  but;</p>
  
  <p>Rails initalizes extremely slow when running commands, i.e. generate, destroy, rake etc.
  Takes about 30-45 seconds to complete command. This will never happens if use Ruby Enterprise Edition or Ruby 1.8.7</p>
  
  <p>Why this happens. Any thoughts?
  Running on Ubuntu 10.10, RVM, Ruby 1.9.2, Rails 3</p>
  
  <p>Thanks.</p>
