我在heroku上运行了几个免费的分层导轨应用，运行得非常好，我没有遇到任何问题。
但是这个
kearns.herokuapp.com
加载速度太慢了！ dyno没有睡觉，因为我每隔几分钟就打它一次。
如果有人有时间，他们可以快速访问，看看他们认为可能是什么？非常感谢！

哇，您的application.css文件（目前为http://kearns.herokuapp.com/assets/application-c515eba896f4bd53f59a05b117a195e0.css）超过16 MB。看起来你在那里包含了实际的图像文件 - 它应该只有图像的网址。

您可以在heroku上添加免费new relic插件，并深入了解您的应用对请求的反应。
