In this paper, evaluation on 7 RDF storage systems with respect to the large data applications is presented. By using the toolkit LUBM-R, 4 different scales of RDF datasets to proceed with benchmark are gotten. The target systems which are evaluated includes two storage systems based on memory (Sesame-Memory and Jena-Memory), two persistent storage systems with RDBMS underlying (Sesame-DB and Jena-DB), and three native RDF approach systems (Sesame- Native, Kowari and YARS). We described how we have performed the evaluation and discussed several issues about the results. We also introduced a combined metric to measure the overall performance of a RDF storage system. And the results show several issues about current RDF storage system.
