Windows.UI.Xaml.WebView bad performance in ARM

    Question

  • Hello,

    I am seeing bad performance in our app due to webview. Often times, webview causes the app to hang when rendering a large table. This cause the OS to evict our app pretty regularly (9 out of 10 times).

    We don't do anything special with webview; the app simply use webview to load the content of a URL.

    Please note that, app-hang which led to eviction can only be reproduced in ARM device (Surface RT).

    What makes it harder; I can't repro it if I attach debugger or in non-release bit; so I am relying on logs to figure out what happened.

    Any idea on how to workaround the issues?

    Thank you much,

    Alex

  • James, just look at any WebView sample on a Surface tablet. For example the Microsoft sample "XAML WebView control sample" exhibits the problem.
