ruby-on-rails - 启用缓存的 Rails 3.2 开发页面加载速度非常慢

Question

我使用Dali gem为我的应用程序开发了低级（模型）缓存。

我通过修改打开了开发中的缓存environemnts/development.rb：

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

#caching
  config.action_controller.perform_caching = true
  config.cache_store = :dalli_store

我的低级缓存效果很好，但现在页面需要几秒钟才能呈现：

它几乎看起来好像在每次访问之前都在预编译页面，这是在错误地尝试使用更高级别的缓存。在生产中，页面活泼而快速。

ActiveRecord 在此页面上运行需要 3 秒，但视图需要 6 秒？

Completed 200 OK in 9407ms (Views: 5669.7ms | ActiveRecord: 3018.3ms)

为了在开发中使用缓存而不杀死我的页面加载时间，我需要启用其他一些设置吗？

导轨 3.2.13
红宝石 1.9.3-p392
