Passenger is the equivalent of something like mod_php or mod_perl but for Ruby (not just Rails). It's pretty good, and contains a fair few optimisations, but it can be a little less flexible than using something like Puma or Thin along with a reverse proxy. Horses for courses, Passenger is less configuration, something else with a reverse proxy (I use nginx for simple stuff) is more flexible :-)
