I recently needed to query tax parcels for a list of parcels within a single town, using IN(…) on a list of tax IDs for the parcels I needed. I ran the query on both the public tax parcels, which covers a portion of the state’s counties, and the parcel centroids, which cover the entire state. In all cases I ran this query in new projects to which I added only those two datasets (both datasets were pulled from FGDBs). Here are the results:
ArcGIS Pro: ~3 minutes for each dataset, for a total of a little under 6 minutes;
ArcMap: near instantaneous for each;
QGIS: perceivable seconds for each dataset, but under 5 seconds for both.
Can anyone shed some light on why I might be experiencing this extreme slowness in ArcGIS Pro? Or is this just the way it is with ArcGIS Pro?
