UWP app performance is slower when compared to Windows desktop application(WPF)

Uma Venkateswararao Achanta 0

I am developing an application in UWP and where I have to download data form network on button click.

In Windows desktop application(WPF) it is taking lower time(11 sec) as compared to UWP(33 sec).

So, does any one has idea on these performance impact on uwp as compared to wpf?

Hi @Uma Venkateswararao Achanta ,

Welcome to Microsoft Q&A!

Which API did you use to download? Could you please provide relevant code snippets to help us further check the problem for you?

Does this behavior happen on different devices and different network scenarios？It would be better if you could tell us the API that you are using in your WPF app and in your UWP app. Are you using the same API to do the download task?

Besides, have you checked the BackgroundTransfer class of UWP?

We are using Listbox/Listview in both UWP and wpf apps, Compared to WPF app, UWP Listbox is taking more time to load and recycle the data.

UWP and WPF may use different networking APIs under the hood. UWP apps are designed to be sandboxed and have restricted access to certain system resources. This may lead to differences in network performance when compared to desktop applications like WPF.

The performance difference between UWP and WPF in your case likely stems from UWP's additional security, sandboxing, and resource management constraints, which can cause slower network or I/O operations. WPF, being a more traditional desktop framework, has fewer restrictions and can access system resources more directly, leading to faster performance. To improve UWP performance, consider optimizing your code, use light fonts, reducing overhead, or using asynchronous operations effectively.
