How long does it take to build the whole index?

		It took about 8-10 hours for me on a 192GB Hetzner cloud machine. The resulting index was just 18GB, so once the index is created it's really efficient and you can easily run it on a small VM.

		I tried the "Australia and Oceania" pbf which is really small and it took ~15min
