Know of an open-source Rails app in need of some performance love?

We've just released the BETA version of our new Ruby Profiler (Stackprof-inspired, but hopefully more readable). To really give it a go, we're looking for some open-source Rails apps that are need some performance love.

If you know of - or our a contributor to - an open-source Rails app that needs some help with slow Ruby, ActiveRecord query optimizations, etc, reach out!
