The [Berlin SPARQL Benchmark (BSBM)](http://wifo5-03.informatik.uni-mannheim.de/bizer/berlinsparqlbenchmark/) is a simple SPARQL benchmark.
It provides a dataset generator and multiple set of queries grouped by "use cases".

We compare here Oxigraph with some existing SPARQL implementations (Blazegraph, GraphDB, Jena and Virtuoso).
We compare here Oxigraph with some existing SPARQL implementations (Blazegraph, GraphDB, Jena, and Virtuoso).
The dataset used in the following charts is generated with 100k "products" (see [its spec](http://wifo5-03.informatik.uni-mannheim.de/bizer/berlinsparqlbenchmark/spec/Dataset/index.html)). It leads to the creation of 35M triples.
It has been executed on a PrevailPro P3000 with 32GB of RAM.
The tests have been executed with a concurrency factor of 16 (i.e. at most 16 queries are send at the same time to the server).

Beware, the graph *y* axis is in log scale to properly display on the same graph systems with very different speed behaviors.

The code of the benchmark is in the `bsbm-tools` submodule. You should pull it with a `git submodule update` before running the benchmark.
To run the benchmark for Oxigraph run `bash bsbm_oxigraph.sh`. It will compile the current Oxigraph code and run the benchmark against it.
You could tweak the number of products in the dataset using the environment variables at the beginning of `bsbm_oxigraph.sh`.
