  Whooops responded with old account. If you run `$ env RAILS_ENV=production rake middleware` you'll see that your final app that gets mounted is actually the "routes" of your app. run CodeTriage::Application.routes Essentially that RouteSet#call wraps every piece of code you've ever written for your app. I think that newrelic is reporting that is the entry point to your app code which makes sense that it takes the longest amount of time. For a better view of request break down I would recommend checking out https://github.com/MiniProfiler/rack-mini-profiler https://github.com/MiniProfiler/rack-mini-profiler. You'll not only see where request time is being spent, you'll see how it "stacks up".
