Data performance tips

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	RouteID (the concatenated routeID in the network feature class) From Date To Date Route Name (if configured)
Calibration Point feature class	Route ID Network ID From Date To Date
Centerline feature class	Centerline ID
Centerline Sequence table	Route ID Network ID From Date To Date Centerline ID
Lookup table	Key Field (if the lookup table is configured with this field)
Event feature class	Event ID Route ID To Route ID (if configured) From Date, To Date
Intersection feature class Note:	Route ID From Date To Date

Since the centerline, calibration point, network, and event feature classes are stored in a geodatabase, spatial indexes are automatically created and maintained. In some circumstances, recalculating a spatial index may improve performance, as described in Modify a spatial index.
