KB10688 - Slow Mini Map speed in a DK application.
The most likely problem is the Mini Map layer is very large. Presenting a huge map file in the Mini Map window can make the application run slow. Because the Mini-Map window is small and not used to preset zoomed-in views, it makes no sense to present in this window a very detailed (large) map file. So better is to use a relatively small file for the MiniMap.
An easy solution is export a small raster file (adjust the compression and resolution to make the raster file relatively small) to use as the MiniMap. A small vector file presenting only the major map features - such as the boundaries of the project extent - also works well.
