スラグのサイズは正常ですか？

Question

私はHerokuでRails 3を使い始めたばかりで、スラッグのサイズ（28MB）がHerokuのRails 2.3.5（5MB未満）と比べてどれほど大きいかに驚いていました。これは正常ですか？これは、reque、aasm、unicornの宝石だけを使用する単純なアプリケーションです。それ以外はすべてデフォルトです。

source 'http://rubygems.org' 
gem 'rails', '3.1.0.rc4' 
gem 'pg' 
# Asset template engines 
gem 'sass-rails', "~> 3.1.0.rc" 
gem 'coffee-script' 
gem 'uglifier' 
gem 'jquery-rails' 

gem 'aasm' 
gem 'resque' 

# Use unicorn as the web server 
gem 'unicorn' 

group :production do 
    gem 'therubyracer-heroku', '0.8.1.pre3' 
end

Answer 1

はい、それは完全に罰金です。特にそれはRails 3.1以降です。これはrubyracerなどのいくつかの大きな宝石に依存しているからです。
