Dev Tools crash when opening Network XHR http Headers with big data of Form Data

[徐明垒]

I open Network XHR to see http Headers , this request have a big data with form data  (14754 byte) .  when form data  expend   Dev Tools will crash ,  cpu  is more then 30% (i5 5200U  win10 8G Memory)

我打开开发者工具查看XHR的请求信息时，如果request中form data内容非常多，查看headers的时候非常慢，直接提示页面无响应。此时我从任务管理器中看到cpu到30%多。

我尝试先把form data项目折叠，然后再次打开，发现headers的内容很快展示出来了，但此时如果点击展开form data，仍然会出现页面无响应，cpu过高的问题。

所以应该是展示form data内容时的代码有性能问题。

1. Accept:
   */*
2. Accept-Encoding:
   gzip, deflate, sdch
3. Accept-Language:
   zh-CN,zh;q=0.8,en;q=0.6
4. Connection:
   keep-alive
5. Content-Length:
   14754
6. Content-Type:
   application/x-www-form-urlencoded; charset=UTF-8

Can you please supply us with a demo of this occurring? It is extremely difficult to diagnose/debug a problem without seeing it occur.

Thanks
