SimpleTimeMeasure

SimpleTimeMeasure is a ruby gem that allows measuring methods without having to alter code of the methods themselves.

Ruby 2.1 or later (it uses Module#prepend introduced in Ruby 2.0 and Process::CLOCK_MONOTONIC introduced in Ruby 2.1)

Add this line to your application's Gemfile:

gem 'simple_time_measure'

And then execute:

$ bundle

Or install it yourself as:

$ gem install simple_time_measure

  class DummyClass
    include SimpleTimeMeasure

    measure_instance_method :test do |result|
      p "instance method :test #{result}"
    end

    measure_class_method :test2 do |result|
      p "class method :test2 #{result}"
    end

    def test
      sleep(1)
      1
    end

    def self.test2
      sleep(1)
      2
    end
  end

  DummyClass.new.test
  "instance method :test {:cpu_time=>60, :wall_time=>1000227, :idle_time=>1000167}"
  => 1

  DummyClass.test2
  "class method :test2 {:cpu_time=>61, :wall_time=>1000214, :idle_time=>1000153}"
  => 2

cpu, wall and idle time are in microseconds
