Clear the cache and then refresh the page, it is estimated that you will be slow to crash. Try a different network environment.

The red part should be TTFB, which is time-consuming to send a request from the client to the first character returned by the server. I understand that the middle should include DNS resolution + establish TCP/IP connection time + server processing time, that is, the network is slow, or slow processing of the server will lead to red part of the time is longer, there should be no front-end anything. The front-end thing should start after receiving the server return.

It's probably a server-side problem.

Tip Next time you want to ignore cache refreshes
You can do it. Disable cache option tick

I'd like to have another new one without a cache.

is not the problem of bandwidth ah, PNG pictures a bit more ah ...
