我需要能够确定为什么视图渲染速度很慢。
在第一台服务器上，它会像这样渲染/设置：
Completed 200 OK in 106ms (Views: 79.6ms | ActiveRecord: 19.8ms)
但是在另一台服务器上：
Completed 200 OK in 8670ms (Views: 8559.7ms | ActiveRecord: 83.7ms)
这是完整的调试日志：

我做的是：
bundle clean --force
rvm gemset empty
rm -rf .bundle
gem install bundler
bundle install --without development test
我不确定究竟是什么解决了这个问题，是宝石，还是现在我安装而没有开发和测试的事实。
