DXR produces the database for its indexing on mozilla-central in about 
3-4 hours on a 4 core machine requiring about 6GB of memory. 
Mozilla-central is perhaps 94K files and around 1GB of size, although 
there is a great deal of non-C/C++ code in that repository. (And one of 
the slowest steps is that we pre-generate the entire HTML, which easily 
adds 20-30 minutes to the timestamp). There definitely seems to be a lot 
of scope to improve the performance of your tool.
