I am big fan of Webview2. I love it, only one problem. It is slow to load a webpage. The old Webbrowser is faster? How is that possible? On the other hand, Edge chromium is super fast. I don't understand that part. Thanks Mark

    Hi,Marklsmail

    To make website run faster, you can try to store pics or pages as a cache. Because most of the time is used to load different parts of the page, like images,

    stylesheets, and scripts.

    Try load css and javascript synchronously, so elements can be loaded without waiting each other.

    You can check this to view more factors that will affect page's loadingf speed:

    And the reason why chorme is faster, it uses javascript V8 engine, so it can run javascripts faster, and it also integrates part of the webkit core, so

    chrome browser opens web pages very fast.

    Best Regards.

    It was my mistake. Webview2 was not initialized and it was taking up to 8 seconds.

    'Start initialisation
    Form OnLoad

    WebView2.Source = New Uri("https://www.google.com/")
