Performance problem - listStatements() takes a long time

[Thorben Wallmeyer]

Hi,

I've got an OntModel with OnModelSpec.OWL_MEM_RULE_INF set that contains 
about 25.000 statements and only 1(!) transitive property. Now I'm 
trying to list all Statements with a special subject (http://myResource) 
by calling

StmtIterator iter = 
model.listStatements(model.createResource("http://myResource";), null, 
(RDFNode) null);

Although execution of this method does not take a long time (some 
seconds) I run in serious trouble/performance issue when calling

iter.hasNext();

This call does not terminate within 5 minutes and I'm asking myself if 
what's wrong. Therefore I'm looking for better solution and your 
suggestions... ;-)


Best,

Thorben
