Public Instance methods

Will first run an empty loop to determine the overhead it imposes, then goes on to yield your block iterations times.

The last yielded return value will be returned upon completion of the benchmark and the result of the benchmark itself will be sent to Log.info

Example:

  class MainController < Ramaze::Controller
    def index
      @users = bench{ User.all }
      @tags = bench{ Article.tags }
    end
  end

This will show something like following in your log:

..
INFO Bench ./start.rb:3:in `index’: 0.121163845062256
..
INFO Bench ./start.rb:4:in `index’: 2.234987235098341

So now we know that the Article.tags call takes the most time and should be improved.
