title: Rails 3.0.3 performing extremely slow on certain views
body: <p>I just upgraded from Rails 2.3.11 to Rails 3.0.3. Overall the performance is fine but some views (about 5 out of a project of about 200 views) perform extremely slow. I tested with both Enterprise Ruby (1.8.7) and Ruby 1.9.2 (p180) getting the exact same behavior.</p>
  
  <p>In newrelic I see that 98% of the performance is taken for the view so it seems not to be database related. Also watching webrick the request itself is very fast, but it takes ages for the request to initially show up in the webrick console (maybe stuck in Rack?).
  I guess it's something I am doing in the view, but I really don't know what...
  I posted the code of one of the critical views below. Maybe someone has an idea?</p>
