Chrome: page loading is slow until DevTools(F12) shows

My env: Chrome 96.0.4664.110 (Official Build) (64-bit) on windows 10

When I open a link in a new page, the page loading is very slow. I can see the loading icon is running but the page keeps blank for a long time(10 seconds or more).

But when I press F12 to show the DevTools window, the page content loads immediately.

So what is the problem, and how to fix it? Many thanks

Same problem for me, finally I realised that it was activated Throttling under the Network tab, and it was selected "Slow 3G" mode, don't know how it has been activated. As you can see there is an alert icon with the Network tab name
