ArcGIS Runtime 100.4 draws basemap really slow when zooming with the mouse wheel

I've created an application for in Visual Studio 2017.Net  WPF and with ArcGIS Runtime 100.4 just using the standard application when you create a new project.

 

I thought the usage of tiled cache should be fast, but using ArcGIS Runtime .Net 100.4.

When I zoom in and out with the mouse wheel it some times take about 4-20 seconds before all the tiles for the extent is loaded. 20 seconds! is really slow. In the Javascript API it is no wait time near this at all. I have 8 GB Mem. 4 core cpu, NVIDIA Quadro K2100M GPU. Anyone experience this? It seems to be loading a lot of tiles. As it sends request for every step I reach during the wheel zoom operation. Shouldn't there be an cancellation of previous requests that doesn't count any more since the extent has changed? There is also the animation on between the zoom levels that slow the zooming process down as well. It should be able to urn this off or at least adjust the time of the animation.
