通过使用剖析工具定位Rails应用程序中特定操作的性能瓶颈。本篇详细介绍了如何配置Rails环境以启用缓存，并利用ruby-prof gem进行性能剖析。

# config/environments/staging.rb
config.cache_classes = true
config.action_controller.consider_all_requests_local = false
config.action_controller.perform_caching             = true
config.action_view.cache_template_loading            = true

config.log_level = :debug

# lib/products_index_profiler.rb
get '/products'
say "GET #{path}"

$ script/server -e staging
$ sudo gem install ruby-prof
$ RAILS_ENV=staging script/performance/request lib/products_index_profiler.rb
