 This configuration defines a benchmark suite that stresstests a triplestore with two workers.
 
 The triplestore is named `fuseki` and is located at `http://localhost:3030/sparql`.
+The dataset, that is used for the benchmark, is named `sp2b`.
 During the stresstest the workers will send SPARQL queries
 that are located in the file `./example/suite/queries.txt` to the triplestore.
 They will stop after they have executed all queries once, which is defined by the `completionTarget`-property.
