Interesting, thanks for doing this, and sharing it so openly.

Do you maybe have the data for your graphs in csv or json? Want to plot my own graphs with it.

Personally I would call it Javascript Performance Benchmark for MongoDB, PostgreSQL, OrientDB, Neo4j and ArangoDB. Which is mentioned at the end of the article under the software section. To be truly a Database Performance Benchmark you would need to interface with the c/native library.

Can anybody recommend other database benchmarks?
