A set of enhancements to benchmark.rb

branch: master
README.md

benchmark_suite

DESCRIPTION:

A set of enhancements to the standard library benchmark.rb

FEATURES/PROBLEMS:

  • benchmark/ips - benchmarks a blocks iterations/second. For short snippits of code, ips automatically figures out how many times to run the code to get interesting data. No more guessing at random iteration counts!

  • benchmark - a cli tool for running multiple benchmarks against multiple rubies.

SYNOPSIS:

require 'benchmark/ips'

Benchmark.ips do |x|
  # Typical mode, runs the block as many times as it can
  x.report("addition") { 1 + 2 }

  # To reduce overhead, the number of iterations is passed in
  # and the block must run the code the specific number of times.
  # Used for when the workload is very small and any overhead
  # introduces incorrectable errors.
  x.report("addition2") do |times|
    i = 0
    while i < times
      1 + 2
      i += 1
    end
  end

  # To reduce overhead even more, grafts the code given into
  # the loop that performs the iterations internally to reduce
  # overhead. Typically not needed, use the |times| form instead.
  x.report("addition3", "1 + 2")
end

REQUIREMENTS:

  • ruby-ffi on MRI

INSTALL:

  • gem install benchmark_suite
