If you are C++ averse, the good news is that you may resolve the real bottleneck independent of the programming language. I've written down some notes about the Overpass API implementation with similar scalability problems: http://wiki.openstreetmap.org/wiki/Overpass_API/Technical_details However, XML parsing (and gzip compression) are heavily CPU intensive. Thus, it might be a good idea to retain these in C++ or getting done in carefully chosen external libraries.
