WPF应用程序在i5处理器计算机上变慢 [英] WPF Application slowing down on i5 Processor machine

问题描述

在WPF中开发的应用程序之一在i5进程笔记本电脑上运行非常慢.
UI在嵌套的Items控件中包含多个用户控件(超过200个).同一应用程序在一台台式机上以良好的性能运行.

以下是笔记本电脑的详细配置，其速度非常慢(渲染用户界面需要50秒):

One of the developed application in WPF is running very slow on i5 process Laptop.
UI contains multiple user controls (200+) in nested Items control. Same application is running with good performance in one of the Desktop machine.

Below is the detailed configuration of Laptop where its very slow (50 sec to render the UI) :
