On my company edge,

We find below on the netlog and cause the browser slow response 

NONE ------ HOST_RESOLVER_IMPL_REQUEST

UDP_SOCKET------[fd3e:4f5a:5b81::1]:53

 

Below capture are form netlog.

Before the request :Time: 2020-11-04 15:02:51.268

On the between, i can see below

Till 2020-11-04 15:03:00.533, the browser move forward:4.png

There are 9 seconds the browser stuck on the 

HOST_RESOLVER_IMPL_REQUEST

and 

UDP_SOCKET DNS query.

 

Do anyone know why those REQUEST and UDP_SOCKET come up?
