Overpass API performance issues

Over the past two days, we’ve conducted a comparative test between the two overpass instances of cartes.app: the one running the main version and the one running @mmd’s fork. Requests from cartes.app were sent randomly to one instance or the other.

  • For all our other request types (without metadata), the improvement is at least 2x (for complex queries) and up to 5x (for simpler queries).

All the details are here:
