rubyのmongrelやthinなんかに変わるhttpdでUnicornとやらがあるのを知った。
ひとまずベンチ取ってみた。rubyでやる専用なのでなにかアプリを書かないと動かないのかな?とりあえずsinatraアプリ書いた。

unicorn-test.rb
require 'rubygems'
require 'sinatra'
set :public, File.dirname(__FILE__)
config.ru
require 'unicorn-test'
run Sinatra::Application
で、unicorn実行。ベンチは
# ab -n 1000 -c 10 -k http://localhost:8080/helloworld.html 2>&1 | tee unicorn.log
で確認した。

unicornの結果
