We are observing severe degradation in the performance of the queries as their size increases? In this context, I want to know if the performance of the query is dependent on the query pattern size? For example, a query with 25 triples in the query pattern is taking nearly 10 secs, to retrieve results from a ontology of size 5000 triples. (no rule bases attached, no inferencing).
Does using query API in Jena Adapter (instead of using sdo_rdf_match() directly) help improve the performance? Also, can u suggest any tuning on the ontology model for speeding up the query execution?
