title: How to make "bundle install" run faster
body: <p>When I need to add a new dependent gem in the Gemfile, then run "bundle install" it seems to take forever (sometimes 7 minutes for me).  How can I make this process faster?  </p>
  
  <p>I did a search on the web, and it mentioned a Gemfile.lock file.  That is appearing for me in my local directory.  But running "bundle install" still takes forever.</p>
  
  <p>I've been learning Ruby on Rails for the past 2 weeks (so forgive the newby question, if the answer is obvious).</p>
