 The dataset used in the following charts is generated with 10k "products" (see [its spec](http://wifo5-03.informatik.uni-mannheim.de/bizer/berlinsparqlbenchmark/spec/Dataset/index.html)). It leads to the creation of 3.5M triples.
 It has been executed on a PrevailPro P3000 with 32GB of RAM.
+The tests have been executed with a concurrency factor of 5 (i.e. at most 5 queries are send at the same time to the server).
