If finding strings quickly is important, use jena text indexing [1]. I recently improved query performance by a factor of 10 by indexing a particular property. I'm not familiar with the benchmark test you mentioned, so I don't know if this is appropriate for your case. Regards, --Paul [1] http://jena.apache.org/documentation/query/text-query.html
