I've been working with imposm and Python, it's fairly easy to parallelise. I've hit a performance problem when trying to associate the coordinates to the ways.

Creating a dictionary from coordinate_id to lat,long and then using it turns out to be really slow.

Do you know of any alternatives that I can use?

Has anyone used a C++ library, or even Scala, or PostgreSQL


Btw, I've been able to iterate through 39GB of PBF, almost the whole globe in 17 minutes on a 32 core machine. That's the performance I'm looking for.

Osmium is a very fast and flexible C++ library for working with OSM data: http://osmcode.org/libosmium/

It supports all types of osm entities such as nodes, ways, relations and even historical osm data. It's published under Boost Software License and therefore free to use.
