Measure and benchmark execution time of your ruby methods. Forget about Time.now - t solution. Use benchmark to see how much time it takes to execute your method.

Sample or usage:

Add this line to your application's Gemfile:

gem 'benchmark_methods'

And then execute:

$ bundle

Or install it yourself as:

$ gem install benchmark_methods

Note: works only for Ruby 2+

Let's say you have sample model User with two methods:

class User < ActiveRecord::Base
  include BenchmarkMethods

  benchmark :generate_report
  cbenchmark :import_users

  def generate_report
    report = reports.create(name: 'My Report')
    report.add_db_data
    report.generate
    report
  end

  def self.import_users(csv)
    CSV.parse(csv) do |row|
      process_import_user(row)
    end
  end
end

Sample Output:

  --> User.create_user_and_comments
      user     system      total        real
  0.010000   0.000000   0.010000 (  0.006721)
  --> User create_test_friend
      user     system      total        real
  0.000000   0.000000   0.000000 (  0.000681)

Gem allows to benchmark ruby methods (instance and class methods).

include BenchmarkMethods - put in your classes, models to add support for benchmarks

benchmark :method_name - benchmark your instance method.

cbenchmark :method_name - benchmark your class method.
