 Using Rails? You don't need to do anything special. If you're using Rack, you need to tell us how to boot your app. In your `perf.rake` file add a task:
 
 ```
-task :rack_load do
-  DERAILED_APP = # your code here
+namespace :perf do
+  task :rack_load do
+    DERAILED_APP = # your code here
+  end
 end
