Until now we have discussed several aspects of the Semantic Publishing Benchmark (SPB) such as the difference in performance between virtual and real servers configuration, how to choose an appropriate query mix for a benchmark run and our experience with using SPB in the development process of GraphDB for finding performance issues.

In this post we provide a step-by-step guide on how to run SPB using the Sesame RDF data store on a fresh install …

Initially we’ve decided to fix some of the benchmark parameters :

  • the dataset size - 50 million triples (LDBC-SPB50)
  • benchmark warmup and …
