Web应用中一直报上面这个错误，不明白为什么？项目中没有请求加载performance-now.js，但不知道为什么后台就一直会请求这个文件。

然后找了好久不知道解决办法，就问[青苗科技][Link 1]的石磊，他告诉了我答案：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FpbmdfZ2Vl_size_16_color_FFFFFF_t_70][]

原来是谷歌浏览器自己请求的！害我研究了好半天。

我换成了火狐浏览器，就不再有performance-now.js的请求错误了。
