Using LDBC-SPB to Find OWLIM (GraphDB™) Performance Issues

ldbc_logoThe Ontotext GraphDB™ (formerly OWLIM) development team integrated the LDBC Semantic Publishing Benchmark (LDBC-SPB) into the development and release process. In this blog post, available on the Linked Data Benchmark Council website, Ontotext staffer Venelin Kotsev describes the benchmark parameters that the team used and the performance results.  Two different local hardware configurations were benchmarked with differing CPUs, memory and storage configurations (SSD vs HDD).  In addition, benchmark results were produced for two Amazon EC2 instances with differing CPUs and SSD storage capabilities.  Full details and the benchmark results can be found on
