Hey,
as I mentioned in an older post, I have quite some performance issues with ArcGIS Pro. Especially when I have to create like 800k polygons or something and put them on a layer it takes ages.
However, I found out that it is much much faster to create a Shapefile (with the DotSpatial library) that contains the polygons and then I can simply add the Shapefile to the project. Speedup is like factor 20.
Now, performance wise I actually have no choice going down this road but I wonder if there are any negative impacts that I don't know of yet? Are there any downsides of shapefiles vs using regular FeatureClasses/FeatureLayers that are stored in the ArcGIS project? Note that I rarely have to modify these objects individually.. instead all of the 800k polygons are nuked and created from scratch when changes are necessary.
Thanks in advance
Christian
