Profiling

Easy steps for CPU profiling a Rails app

  1. add ruby-prof to your gemfile (https://github.com/ruby-prof/ruby-prof)
  2. grab kcachegrind or qcachegrind (brew install qcachegrind graphviz on os x)
  3. plop development_profiler.rb in lib in your app
  4. wrap your questionable code in a prof block
  5. open the file in qcachegrind (It'll live in tmp/performance in your app)
