Rails Application#call is very slow


I'm seeing this Application#call take anywhere from 500 to 1500ms on every call which is soaking up memory on my Heroku dynos and causing timeouts. Any idea how to figure out what's inside this Application#call? Stuck on ideas. I replaced our app name with AppName.

  • I looked at the deployments when this first started happening. Turns out it was a beta gem version from Scoutapp.com
