Currently during Routing "fast"-Mode is used to determine the routes.

So the Azure lookup has to be done during "calculation", this will cost some time.

Routes could be prefeteched and stored in distance_matrix:

  1. store a stale entry during "fast"-Lookup
  2. free worker thread fetches all stale entries an does lookup.
  3. during calculation the cached distance is available.
