Use network tool and performance tool in browser's DevTools to find out what is causing the slow.
It should be possible to isolate whether network is slow or whether javascript is the cause

In the official WebView2 example, WebView2APISample,
added code to debug output the time interval from the beginning of page loading to the completion of loading.
Loading the following two websites takes more than 10 seconds each, and the debug output is as follows:

2024-03-05T09:01:12.0933333+00:00 Users may access any website, and analyzing performance only for these two websites is not sufficient.
With the use of WebView2, the user experience is slower compared to Edge.
Is there any way to make WebView2 load web pages faster?
Similar speed to Edge would be acceptable as well.
