For fun, to see if there would be a difference between 32-bit ArcGIS for Desktop and 64-bit ArcGIS Pro, I ran a simple geoprocessing task with both.
I have a modelbuilder model that:
- Creates a new mosaic dataset in a file geodatabase
- Adds rasters to the mosaic dataset
- Defines and builds overviews
- Defines mosaic dataset NoData
On the same computer, I ran this model in ArcGIS for Desktop Advanced and then I ran it in ArcGIS Pro.
Processing Time Results:
ArcGIS for Desktop = 7 minutes 15 seconds
ArcGIS Pro = 11 minutes 23 seconds
I’m surprised that the 64-bit ArcGIS Pro application took 57% longer to run the model and process the data.
That's interesting. I did some testing with individual geoprocessing tools (mostly raster processes). These tools took at least 5 minutes to run, and I found no meaningful differences between Pro and Desktop (<5%).
