ContentPage包含列表视图在Android上显示非常慢

我不确定这是我的问题还是Xamarin的问题。在iPad上，我的应用程序可以在ListView中加载包含数据列表的页面。 ListView内的View Cell可能稍微复杂一些。它包含一个配置文件图像，使用一些较小的图标，它们使用FFImageLoading。ContentPage包含列表视图在Android上显示非常慢

在iPad上，当我点击第一页的单元格进入包含数据列表的下一页时，它会非常顺利地加载。在Android上，当我点击某个单元格进入下一页时，点击的检测速度很慢，并且ListView的加载时间也非常缓慢。

反正有提升性能吗？我认为这是我从SQLite加载的数据。但是，我注释掉ListView上的ItemsSource后，加载时间很好。

这是我用来显示单元格的数据素材。
