Documentation suggestion: Graph query benchmarks for a clustered configuration

[whlavina]

I wish to suggest that you expand benchmark results for ArangoDB to cover graph queries, for a multi-node clustered configuration, perhaps guided by:

• Linked DataBase Council (LDBC), the graph & RDF benchmark reference
• Graph Benchmark: Comparing and Understanding Graph Databases

You do provide NoSQL Performance Benchmark 2018 – MongoDB, PostgreSQL, OrientDB, Neo4j and ArangoDB, but:

• The benchmarks may benefit from additional test cases as developed in the 2 references above, to better model potential real-world scenarios.
• It looks like the reported ArangoDB benchmark results are for a single-node instance, rather than a multi-node cluster. Varying cluster size as a parameter, would help clarify the scalability expectations, and may also help reveal performance issues; see e.g. #6142 and #8806.
