Description

Building geometries for relations, in particular multipolygons with more than 500 members, takes too long.

This relation is a good example: https://www.openstreetmap.org/relation/13005167

Research direction

Start by profiling relation geometry building with the linked OpenStreetMap relation 13005167, especially the case with more than 500 members. Done means multipolygon relation geometries are built faster, but the issue does not name a source file, test, or benchmark to run.
