Proper tuning of the database and the implementation of attribute and spatial indexes during the data loading operation will enhance the performance of any application. This is especially true for ArcGIS Roads and Highways because of the extensive data processing steps involved.
For optimal performance from mapping events in Roads and Highways, make sure that your database has the appropriate indexes created. You can use the Add Attribute Index geoprocessing tool to create indexes.
|Table name||Multicolumn attribute index fields|
LRS Network feature class
Calibration Point feature class
Centerline feature class
Centerline Sequence table
Event feature class
Intersection feature class
Since the centerline, calibration point, network, and event feature classes are stored in a geodatabase, spatial indexes are automatically created and maintained for you. In some circumstances, recalculating a spatial index may improve performance, as described in Modify a spatial index.
