I tried the link you send. With 55 Billion+ live triples, the response time is very much impressive. 

However, I must say that I am lost on viewing the results -- the presentation is not designed to anybody outside of the RDF community!

By the way, how you compare your approach to neo4j? I am planning for a research prototype that needs ontology-driven query of millions of nodes for treatment comparisons. Your inputs are appreciated!

Also note that there is a live 55 Billion+ triples instance of the LOD 
Cloud cache that showcases what's always been possible re. Linked Data, 
RDF, and machine readable Entity Relationship Semantics.
