In the 2.4 release of the Esri Utility Network Package tools the "Apply Asset Package" tool (Apply Asset Package—Tool Reference | ArcGIS Solutions ) was able to make use of multiple cores during the data loading process in order to reduce data loading times.
In the 2.5 release of these tools this appears to no longer be the case. This means that small datasets that used to load in 30-45 minutes are now taking upwards of 8 hours.
Is this a known issue? Is there a workaround? In particular I need to have the append and import associations tools run in parallel as loading a single association file for a medium sized dataset can take 1-3 hours (my current dataset has 20 association files!).
