    Rails has benchmark helper to quickly test the time of execution of a given piece of code. Active Record, Action Controller and Action View libraries provides a benchmark() method to measure the performance of code.

    Example: Model(Active Record):

    1. User.benchmark("Creating user") do
    2.   user = user.create("name" => "Jony")
    3.   user.create_stories("content" => "Test")
    4. end

    While execution of the above piece of code something like this Creating user (100.3ms) can be seen in the log file.Here benchmark() is a class method of the model User.

    Controller(Action Controller):

    1. def process_stories
    2.   self.class.benchmark("Processing stories") do
    3.     @stories = current_user.stories
    4.     Story.cache_story_feeds(@stories, "myfeed-#{current_user.id}")
    5.   end
    6. end

    Views(Action View):

    1.     <% benchmark Show story feeds' do %>
    2.           <%= show_story_feeds %>
    3.     <% end %>

    In the log file output will be Show story feeds (191.5ms).

    This benchmark() method accepts logger level(:debug, :info, :warn, :error) as optional parameter. Default is :info. Thus we can modify the above code as:

    1. <% benchmark Show story feeds' , level: :debug do %>
    2.           <%= show_story_feeds %>
    3.     <% end %>

    If we pass silence: true as the third argument all logging activity except the time information for the block will be silenced.
