Okay, so you don't have an automated procedure in place yet.  Understood.  When you get to that point, check out the Create Network Dataset From Template tool: https://desktop.arcgis.com/en/arcmap/latest/tools/network-analyst-toolbox/create-network-dataset-from-template.htm  I think this might be more efficient and easier to do than what you're suggesting with truncating and re-populating tables. Taking another wild guess here, which is kind of a long shot: When you make edits to the features of a network dataset, the network will create an internal table of "dirty areas" indicating which parts of the network have been changed.  When you build the network, it only builds the dirty areas instead of the whole thing.  This is intended to make the procedure more efficient because if you have, say a nationwide network dataset but you only edited one neighborhood, it can just leave everything except that neighborhood alone. However, if you've made wide-sweeping edits, such as replacing all the streets with different streets in a different geography, you might have built up a sizable dirty area file.  Possibly the Build process is actually slower if it's trying to sort through all these dirty areas and take care of them rather than just rebuilding the entire network as if from scratch. But, that's just a guess which may or may not apply to your situation. Do you get the slow behavior if you put your streets in a fresh geodatabase with a fresh feature dataset and create the network dataset completely from scratch?  If not, then the above might describe what's going on.  If it's still slow in this case, then something else is probably weird with your data.  I would suggest you call Support so they can look at the data for you and diagnose the problem. ...

In general, I wouldn't expect building a network with 70,000 edges to take more than a few minutes. You don't specify, but since this is an automated procedure you're developing, I presume your network dataset is in a file geodatabase and not a shapefile?  File geodatabase will likely be faster than shapefile. Check your network's source feature classes and make sure they have a spatial index.  If they don't, that's probably why everything is slow. If that's not it...can you describe your procedure in a bit more detail?  For example, are you using the Create Network Dataset From Template tool, or have you developed some other method (via ArcObjects, for example) for creating the network dataset? ...

Unfortunately, we didn't make it for 2.4, but we are now aiming for 2.5. ... View more

No, there's no way to do that.  If you want to append the new route segments to the existing ones, you could just generate the route for the new stops and then merge the features with the existing ones. ... View more

Would it be possible for you to share your facilities with me so I can test your script?  I can't tell from looking at it what's going wrong, but I'd like to get to the bottom of it.  I don't need your network dataset. ... View more

When you use the load() method to load your input features into Facilities, use field mapping to assign your breaks field to the Breaks field in Facilities. Alternatively, if you are loading facilities using an insert cursor, you just need to set the desired values directly into the Breaks field. load() and insert cursor are just two ways of accomplishing the same thing - inserting facilities. ...

Hi Andrew.  Glad you're putting nax to good use. Documentation for the Service Area input fields is here: https://pro.arcgis.com/en/pro-app/arcpy/network-analyst/servicearea-input-data-types.htm ... View more

Yes, unfortunately you still can't create a network dataset from scratch in Pro as of 2.4.  We're trying for the next release. ... View more

There's probably a problem with the way you've configured your restriction attributes.  Can you post a screenshot of your restrictions and their evaluators? ... View more

Can you post a screenshot of your attribute table?  Also, are you using a local on-disk network dataset, or are you using the ArcGIS Online services as your network data source? In general, Pro pays attention to the Sequence field in the Stops table.  If the stop you want last is last in the table but has a Sequence value that is less than some other stop, then it won't end up as last in the analysis. ...
