title: is mod_rails or Phusion Passenger finally the answer to Ruby on Rails Deployment?
body: <p>I read from some books that Phusion Passenger is the answer to easy Ruby on Rails deployment.  But my friend said that first there was Apache + bunch of Mongrels, and then lighttpd, and then nginx, and now Passenger, and it seems endless...</p>
  
  <p>he also said he uses dreamhost which uses Passenger, and sometimes he sees his request not being processed.</p>
  
  <p>So I wonder if Passenger is the final answer to RoR deployment?  do you use it and used the "ab" command to test if the site is doing quite well?</p>
