Here is another approach by using PolygonNeighbors_analysis, which was introduced at ArcGIS 10.1. # fc : Feature class to-be-processed # ID_field : Unique ID field in the feature class on which groupping will be based # neighbour_table : Table location where the Polygon Neighbor results will be saved, # ...

You would have to be a on a fairly low-tech machine, or be zooming/panning via automation in order to have issues rendering only two XYZ layers. I suspect your issue is related to something else. If it was an actual issue, you could employ a bounds/extent trigger to stop rendering and halt network traffic for tiles that are out of view. That being said, ...

A faster way to accomplish this is with a spatial join for step 3, once your polygons have their unique number. Let's say UID is the field name for your unique ID from your dissolve polygons, Dissolve is your dissolve polygons, Polies is your target polygon, and outFC will be the full path of your resulting feature class. Below I get a little fancy with ...

The trick here to work with smaller extracts from massive flow direction raster. The script below does exactly this, growing processing extent from initial buffer (radius) around point equal to (1000*cell size). When no growth in catchment size found it proceeds to next pour point, saving output in wshed_0000.shp, wshed_0001.shp etc in outFolder folder :) ...

These options may help or may not depending on your hardware configuration and license/tool availability. (1) You could look into enabling 64-bit background processing to help things along. If these tools are able to utilize it, it could potentially shave some time off for you. (2) You might be able to (depending on the availability of the tools and your ...

If your model does what you need, Modelbuilder already has a built-in function that will sort of do what you're asking for. In the Modelbuilder window, go to Model > Export > To Python Script. That will convert your model steps to the equivalent Python commands in a script file. This process is automated by ArcGIS, so it doesn't necessarily export the ...

From ModelBuilder: Model > Export > To Python Script... This will create a python script that does exactly what you specified in the model. You can then look at it and modify it as desired. I'm not sure you will get any speedup from this, since using python calls all the same tools as ModelBuilder, so the watershed tool will still take the same amount of ...
