I have a Web Map that I created in ArcGIS Online with data that is hosted on our server. When you pan around and zoom in and out in the map viewer, things draw really fast. I have created an Application with Web AppBuilder Developer on our server with this map and when you pan, things draw fast, but when you zoom in and out, it takes quite a while for the drawing to render. Why is there such a lag in drawing in the Application? Is there something I can do to speed this up? It doesn't matter if they are images or just vectors either. Thanks so much for any help.
