We are having performance issues in NA Solver OD Cost matrix using ArcGIS 10.
In 9.3.1 for 123 locations it took 1-2 minutes for building the matrix. Using ArcGIS 10, SP4 it is taking 1 hour 4 minutes to build the matrix. We verified this in ArcMap10 and it is taking 1-2 minutes only.
Do we need to make any changes in settings of NASolver?
