 - **Precalculate Network Locations** (Python: *Precalculate_Network_Locations*) - When you solve a network analysis, the input points must "locate" on the network used for the analysis. When chunking your inputs to solve in parallel, inputs may be used many times. Rather than calculating the network location fields for each input every time it is used, it is more efficient to calculate all the network location fields up front and re-use them. Set this parameter to True to pre-calculate the network location fields. This is recommended for every situation unless:
   - You are using a portal URL as the network data source. In this case, pre-calculating network locations is not possible, and the parameter is hidden.
   - You have already pre-calculated the network location fields using the network dataset and travel mode you are using for this analysis. In this case, you can save time by not precalculating them again.
+- **Spatially Sort Inputs** (Python: *Sort_Inputs*) - A Boolean indicating whether to spatially sort origins and destinations prior to commencing the parallel solve.  Using sorted data will improve the efficiency of the chunking behavior significantly, and it may reduce the number of credits consumed if you're using a service that charges credits.  If your input data is already sorted, then sorting is not useful, and you should set this parameter to false.  Otherwise, you should set his parameter to true.  Note, however, that spatial sorting is only available if you have the Advanced license.  Spatial sorting will be skipped automatically if you don't have the necessary license, and the parameter will be hidden in the tool dialog.
