Well at the very least it means the app uses the production database
instead of the development one (as dictated by database.yml). It also means that config/environments/production.rb is loaded instead
of config/environments/development.rb Some settings also have a different default (eg the logger level)

Hi    thanks for the reply..So is there large speed differnce in development and production mode? Also to run my server in production mode I have to do any of the below ./script/server RAILS_ENV=production or ./script/server -e production

Is that all done?Nothing other setup is needed?

Well it depends on the settings you have made. By default there is a
big difference because with the default settings your app's code is
reloaded on each request.

Also, some plugins behave differently depending on the environment. For example, the exception_notification plugin won't send you an email you when an exception occurs if you're running in development mode, but does in production mode.
