[wo1234]

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:

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?

@wo1234 Thanks for reaching out. It looks like you also posted this on answers.microsoft.com (The edge having slow response. - Microsoft Community) so I will hand it over to our rockstar AMC CM, @Alexandra-R, to help you and the OP over there. (It looks like @Eric_Lawrence may also have some additional Chromium context.)
