node-methodmissing benchmark

install dependencies

% npm install

run

% coffee bench.coffee
% coffee bench.coffee > result.txt

みどころ

• methodmissingを適応したオブジェクトは、通常の関数呼び出しが遅くなる
  • methodmissingな関数よりも遅くなる

bench.coffee

method_missing = require 'methodmissing'

bench = (title, times, func)->
  ## console.log "== #{title} #{times} times : start"
  start_at = new Date()
  for [0...times]
    func()
  elapsed_time = new Date() - start_at
  console.log "== #{title} #{times} times : end - #{elapsed_time}(usec)"
