RoutePairsGroupSize

This property can be used to control how the RoutePairs method works:

In the default state, the routes are calculated one by one.

If the value is >1, you should keep the LL1 list sorted according to location and the calculations are done using isochrones instead.

This can mean lot faster calculations, easily a factor 10, depending upon size of groups, size of network, geographical spread of locations etc.

A suggested value is 3-5.

If NoDriveThrough is true, it will calculate one by one, in any case.

Default: 0

Type: integer
