simplest_benchmark

Benchmark your code fastest, simplest and get pragmatic results.

• Perfectly formated for get into an spreadsheet and analyze it.
• Inegrated with Rails logger
• Not Rails ? don't worry, it creates a cutom simplest_benchmark.log log file
• only two methods: sb_begin, and sb_end

It's so simple:

Installation

gem install simplest_benchmark

or in your Gemfile:

gem 'simplest_benchmark'

Usage

Simple use

require 'simplest_benchmark'

class MySlowClass
  include SimplestBenchmark

  def slow_method
    var = get_some_value
    sb_begin('heavy work')
      some_hard_work
    sb_end('heavy work')
  end
end

Nested use

require 'simplest_benchmark'

class MySlowClass
  include SimplestBenchmark

  def slow_method
    var = get_some_value
    sb_begin('heavy work')
      some_hard_work
    sb_end('heavy_work')
  end

  def some_hard_work
    sb_begin('heavy work 1')
      hard_work_part1
    sb_end('heavy work 1')

    sb_begin('heavy work 2')
      hard_work_part2
    sb_end('heavy work 2')
  end
end

Results

Results go to Rails log file, or to simplest_benchmark.log file. You can simply do

cat log/development.log | grep DEBUG

and obtain something like:

DEBUG   2015-11-19 17:13:24 -0300       1447964004.003463       BEGIN   0       heavy work

• field1: DEBUG text
• field2: timestamp of event
• field3: timestamp in float format
• field4: BEGIN or END event
• field5: level of deepness: For nested usage, each nested sb_begin gonna +1 this number
• field6: label identifier
• field7: amount of seconds transcurred between last sb_begin and current sb_end call.

it is all. Enjoy.
