in case of the downloaing from the free server: https://overpass-api.de/ it should be slow or uncertain

this is a list of companies that could offer osm data download services in a reliable way https://wiki.openstreetmap.org/wiki/Commercial_OSM_Software_and_Services what the project needs is an Overpass server that has the ability to provide data from a certain arbitrary boundingbox, currently our solution uses free servers

@bertolla I'm just uploaded a one file version of osm data here: https://cloud.opendatahub.bz.it/index.php/s/MRsMxr8wkNW3Xpd?path=%2F osm-all.tar.gz 294.3 MB(uncompressed is 3GB) you can try to use it for building a new Graph.obj faster. Uncompress it inside data directory and the other .osm files must be moved out of the given directory In this way the creation time of the graph could be reduced.

I did so. The graph calculation now takes around 7 minutes instead of ~ 10

Damn! I'm hoping for less time :(
