 STR_CONFIG_SETTING_LINKGRAPH_INTERVAL_HELPTEXT                  :Time between subsequent recalculations of the link graph. Each recalculation calculates the plans for one component of the graph. That means that a value X for this setting does not mean the whole graph will be updated every X days. Only some component will. The shorter you set it the more CPU time will be necessary to calculate it. The longer you set it the longer it will take until the cargo distribution starts on new routes.

When a recalculation is started, a thread is spawned which is allowed to run for this number of days. The shorter you set this the more likely it is that the thread is not finished when it's supposed to. Then the game stops until it is ("lag"). The longer you set it the longer it takes for the distribution to be updated when routes change.
