bnchmrkr

i hate the name too, but..

Bnchmrkr (Benchmarker) is a tool to help benchmark different method implementations

it is driven by Benchmark

usage

pre-built gem installation (stable)

RubyGems

gem install bnchmrkr
irb
...
irb(main):001:0> require 'bnchmrkr'
=> true

from-source installation (latest)

cd bnchmrkr
rake clean build
gem install pkg/bnchmrkr*.gem

=> true

examples

tester = Bnchmrkr.new({
  :count_to_1k   => lambda { 1.upto(1000).each   { |i| i } },
  :count_to_5k   => lambda { 1.upto(5000).each   { |i| i } },
  :count_to_10k  => lambda { 1.upto(10000).each  { |i| i } },
  :count_to_50k  => lambda { 1.upto(50000).each  { |i| i } },
  :count_to_100k => lambda { 1.upto(100000).each { |i| i } },
}, 1000)
