Have you profiled the app? Which parts of it seem to be slow? Also, I don't
think that a few numeric attributes for ~50000 vertices should eat up 7.7 GB of
memory with the C attribute handler. Can it be the case that your app is
leaking memory somewhere?

If it is not highly confidential, send me a self-contained example that 
your problem and I'll take a look at it.
