Rails 3 rendering is so slow

I recently booted up an old version of a Rails project of mine, which uses Rails 2.3.11 and realized that Rails 2.3 is much faster running almost the same code as the recent version.

My question: Is Rails 3 slower than Rails 2? Especially when rendering lots of partials? The old version never really exceeded 300ms for a request, Rails 3 takes 600ms and more, sometimes even 2 seconds. Any workarounds known? Or should I move my partials into helper methods (generating the html)? And no, downgrading is not an option!

Greetings, Mario

How are you rendering your partials? Rails in development mode can be quite slow. You can try giving this gem a try by adding this to your Gemfile: gem 'rails-dev-boost', :git => 'git://github.com/thedarkone/rails-dev-boost.git', :require => 'rails_development_boost'.

If you are running your partials via a collection, you can always do something like <%= render @posts %> for better performance gains.

Hope this helps!
