I think that 2.5 minutes for these simple layers is too much. Because the processing time per layer did not vary much, no matter how much data was generated (13312 bytes .img of ferry routes, 986624 bytes of bus routes), I would guess that parsing is dominating the execution time, and the processing time would reduce from N*2.5 minutes to about 2.5 minutes if we implemented a 'multiple output tiles from one input tile' feature.
With --ignore-builtin-relations, the time reduces to N*2 minutes, give or take a couple of seconds per layer. I will next try how I could generate multiple type=route relation tiles at once (split by route=*), using a single parsing stage. Marko
