There's not a lot details there to go on.
As a general principle Pellet is a complete DL reasoner whereas the jena
OWL rules are much more limited. If you want complete and performant DL
inference then use a proper DL reasoner. In simple cases the jena rules
can give useful results in reasonable time and they serve a useful
purpose in many settings. However, for hard cases they can easily fall
into exponential behaviour. Even just equality reasoning can be
problematic. Ontology size it not itself an indication of reasoning
complexity.

Hi, I am trying to run a very small ontology with Jena OWLReasoner using Jena
libraries in Eclipse and it runs forever. The memory was initially an issue,
but after I added extra 16GB of RAM, it was still working after 24 hours. This
is an ontology that runs in under a second with Pellet. Any idea why is that? I
will really appreciate any suggestions.
Thank you SO MUCH.
Regards, Neli.
