我使用Dali gem为我的应用开发了低级（模型）缓存。
我通过修改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渲染：

在每次访问之前，看起来好像页面正在进行预编译，这是为了在更高级别使用缓存。在制作过程中，这些页面非常快速。
ActiveRecord在此页面上运行需要3秒钟，但视图需要6秒钟？
Completed 200 OK in 9407ms (Views: 5669.7ms | ActiveRecord: 3018.3ms)
我是否需要启用一些其他设置才能在开发中使用缓存而不会中断页面加载时间？
