I just wanted to post out something I learned today. This is a link to my reply on stackoverflow:

[Stackoverflow](http://stackoverflow.com/questions/17025563/how-to-get-mini-profiler-to-start-in-rails/26369990#26369990)

The gist of it is that there is a conflict with Rack::Deflater because it manipulates the body in a way that the profiler is not able to insert itself. I hope that helps some of those that have been struggling to see it work on rails.

This is actually covered in the Readme (I added it a few months ago 🙂 )
