ruby-on-rails – Rails 4.2应用程序开发速度非常慢

现在,我已经把头撞在那个墙上几天了.
我的应用程序在开发模式下运行速度超慢.花费大量时间来提供资产(尤其是图像).每个请求都非常慢,最多需要7秒才能加载一个简单的50kb jpeg.总页面加载时间可能长达几分钟……

我怀疑有一个链接自动加载代码,因为当我打开类缓存时,我的东西加载速度要快得多(最多几百毫秒).这不是解决方案,因为我需要编码,每次进行更改时都无法重启服务器.

这是我的config / development.rb

Rails.application.configure do
  # Settings specified here will take precedence over those in config/application.rb.

  # In the development environment your application's code is reloaded on
  # every request. This slows down response time but is perfect for development
  # since you don't have to restart the web server when you make code changes.
  config.cache_classes = false

  # Do not eager load code on boot.
  config.eager_load = false

  # Show full error reports and disable caching.
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false
  config.reload_classes_only_on_change = true

  # Don't care if the mailer can't send.
  config.action_mailer.raise_delivery_errors = false

  # Print deprecation notices to the Rails logger.
  config.active_support.deprecation = :log

  # Raise an error on page load if there are pending migrations.
  config.active_record.migration_error = :page_load

  # Debug mode disables concatenation and preprocessing of assets.
  # This option may cause significant delays in view rendering with a large
  # number of complex assets.
  config.assets.debug = false

  # Asset digests allow you to set far-future HTTP expiration dates on all assets,# yet still be able to expire them through the digest params.
  config.assets.digest = true

  # Adds additional error checking when serving assets at runtime.
  # Checks for improperly declared sprockets dependencies.
  # Raises helpful error messages.
  config.assets.raise_runtime_errors = true

  # Raises error for missing translations
  # config.action_view.raise_on_missing_translations = true

  config.action_mailer.default_url_options = { host: '127.0.0.1',port: 3000 }
  # email sending process
  config.action_mailer.perform_deliveries = true
  config.action_mailer.delivery_method = :test
  # Defaults to:
  # config.action_mailer.sendmail_settings = {
  #   location: '/usr/sbin/sendmail',#   arguments: '-i -t'
  # }
  config.action_mailer.perform_deliveries = true
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.default_options = {from: 'no-reply@example.com'}
  config.web_console.whitelisted_ips = '0.0.0.0/0.0.0.0'


end

和initializers / assets.rb

# Be sure to restart your server when you modify this file.

# Version of your assets,change this if you want to expire all your assets.
Rails.application.config.assets.version = '1.0'
# Rails.application.config.assets.precompile += %w( jquery.Jcrop.min.scss )
# Rails.application.config.assets.precompile += %w( jquery.Jcrop.min.js )
# Rails.application.config.assets.precompile += %w( flat-ui.css.bak )
# Rails.application.config.assets.precompile += %w( bootsrap.css.map)
# Add additional assets to the asset load path
# Rails.application.config.assets.paths << Emoji.images_path

# Precompile additional assets.
# application.js,application.scss,and all non-JS/CSS in app/assets folder are already added.
# Rails.application.config.assets.precompile += %w( search.js )

Dir.glob("#{Rails.root}/app/assets/images/**/").each do |path|
  Rails.application.config.assets.paths << path
end

任何见解都将非常感谢！
