An iterations per second enhancement to Benchmark that includes memory allocations

benchmark-ipsa

An iterations per second enhancement to Benchmark that includes memory allocations, based on benchmark-ips. It makes benchmarks closer to what the go bench tool has.

Memory allocation report is supported for Ruby 2.1 and up, for older ruby versions it degrades to the normal benchmark-ips behavior.

Installation

Add this line to your application's Gemfile:

gem 'benchmark-ipsa'

And then execute:

$ bundle

Or install it yourself as:

$ gem install benchmark-ipsa

Usage

require 'benchmark/ipsa'
Benchmark.ipsa do |x|
  x.report('foo 1'){
    arr = ['1', 2]
    sleep 0.1
  }
  x.report('foo 2'){
    sleep 0.1
  }
end

Results:

Allocations -------------------------------------
               foo 1       2/0  alloc/ret        1/0  strings/ret
               foo 2       0/0  alloc/ret        0/0  strings/ret
Warming up --------------------------------------
               foo 1     1.000  i/100ms
               foo 2     1.000  i/100ms
Calculating -------------------------------------
               foo 1      9.675  (± 0.0%) i/s -     49.000
               foo 2      9.585  (± 0.0%) i/s -     48.000
