My team also faced the slowness of app when upgraded to Rails 3.1 from Rails 2.3.8, using Ruby 1.8.7.
We upgraded to Ruby version to 1.9 to overcome the slowness. The app runs better in Ruby 1.9.2 with Rails 3. - Neethu -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
