Ruby on rails Rails 5生产应用程序间歇性地使用nodejs峰值

我有一个Rails 5应用程序，在生产服务器上，有时用户会访问该站点，浏览器会不停地旋转。每当发生这种情况时，我们都使用ssh连接到盒子中，然后运行top，我们看到nodejs占用了CPU。这种情况发生在box正常运行一段时间之后，也就是说，这不是用户在部署后第一次访问站点。我之所以提到最后一部分，是因为我们有一个假设，可能是用户第一次点击视图时，一些资产正在被编译（即使我们没有特定于视图的资产）。以下是发生这种情况时top的输出：

3707 deploy    20   0  998724 119820  14060 R  68.4  3.0   0:02.95 nodejs                                                                                                                                     
3702 deploy    20   0 1023804 152868  14020 R  66.8  3.8   0:03.70 nodejs                                                                                                                                     
3712 deploy    20   0  958788  77108  13800 R  17.6  1.9   0:00.53 nodejs     

有人知道为什么nodej在对Rails应用程序的常规生产访问期间（我指的是“常规”访问，而不是异常访问，比如部署后的第一次）会出现这样的峰值吗

谢谢， 凯文

结束

事实证明，这是由以下内容指定的回退：

config.assets.compile = true

我在这里写了一篇解释解决方案的文章：

发布您的生产环境。配置文件。@bkunzi01更新了问题，谢谢
