Data performance tips

Database tuning and the implementation of attribute and spatial indexes during the data loading operation can enhance the performance of any application. This is especially true for data intensive applications such as ArcGIS Roads and Highways.

For optimal performance in Roads and Highways, ensure that your database has the appropriate indexes created. You can use the Add Attribute Index 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	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 can improve performance.
