[Answered ]-Django app – deploy using UWSGI or Phusion Passenger

Production performance is pretty the same, so I wouldn’t worry about that. uWSGI has some advanced builtin features like clustering and a cron API while Phusion Passenger is more minimalist, but Phusion Passenger provides more friendly tools for administration and inspection (e.g. passenger-status, passenger-memory-stats, passenger-config system-metrics).
