As a user, I would like to have warnings about the landuse polygon size that will greatly slow down the performance in XPSWMM.
Large number of land use polygons can greatly slow down the performance of XPSWMM, it can take up to 10 min to open and save a model. Ideally this issue should be fixed. Before that happens, if XPSWMM can warn the user for the large size of the landuse polygons, and provide links to ways to simplify the polygons or move landuse out as a reference layer, that will save the users lots of time.

GUI and ancient storage system need to be fixed. Too much is a 32MB xp file that cannot be compressed to clean out old data. This limit is extremely easy to hit even using the lowest level license level. We don’t need a warning; we need it fixed. Application needs refresh to modern GUI and storage system.
Age makes this a great model with lots of functionality, but also very difficult and costly to use.
