I am not aware of anyone keeping aggregate statistics.  

If you would like a simple example of C++ usage --- via the Rcpp package I
maintain --- then I'd recommend the Earth Mover Distance package on R-Forge
which wraps a single function providing the Earth Mover Distance metric:

 https://r-forge.r-project.org/projects/earthmovdist/

and the SVN sources are here

 https://r-forge.r-project.org/plugins/scmsvn/viewcvs.php/pkg/?root=earthmovdist

A more complicated example is e.g. RQuantLib on R-Forge and CRAN.
