The Neo4j engineering team has completed a series of tests in various environments and workloads, sharing the results with users. The tests were conducted on three different server types: AWS Ubuntu instances, dedicated hardware low-end servers, and dedicated hardware medium-level servers. The performance was tested across several workloads, including internal performance testing workloads, store sizes varying between 1-200GB, realistic read and write workloads against real database stores, targeted micro-benchmarks, and very large data imports. The tests were run on the latest patch release of all supported Neo4j versions, including 3.0.12, 3.1.7, 3.2.9, and 3.3.2. The results show negligible performance impacts across different server types and workloads, with some substantial improvements in Neo4j performance from versions 3.1 → 3.2 and from 3.2 → 3.3. The team will continue testing as new OS and firmware patches become available to evaluate their impact on the product's performance.
