    Resolution: Won't Fix

While a Fastlane might improve perfoamce, no sparql engine is known that is likely to be faster

> The Scalability of the integrated SPARQL engine isn't very good.  Some test with big
graphs demonstrate this problem. 
> A Query over a big Graph (120 MB) needs more than 45 seconds with SPARQL. The same "query"
build with graph.filter(triple) calls, needs only 1-2 msec - quite faster. 
> research with Manuel Innerhofer shows, that the problem is the hasnext() method of the
SPARQL  resultset.
