Memgraph vs. Neo4j: A Performance Comparison

The blog post presents a performance comparison between Memgraph and Neo4j, two graph databases with different architectural foundations, highlighting that Memgraph, written in C++, significantly outperforms Neo4j, which is based on the JVM. The benchmarking, conducted with a range of concurrent Cypher queries, reveals that Memgraph is up to 120 times faster than Neo4j while also being more memory efficient, using only a quarter of the memory. Memgraph's superior performance is evident in latency and throughput tests, showing it handles a wider variety of queries more efficiently under concurrent workloads. Additionally, Memgraph offers snapshot isolation out-of-the-box, compared to Neo4j's default read-committed isolation, which simplifies building applications that require robust concurrency control. The blog emphasizes the importance of careful benchmarking and invites readers to explore the methodology and results, which are publicly available for verification.
