TL;DR
Recent benchmarks tested SurrealDB 3.x against major databases like Postgres, MongoDB, Neo4j, and Redis using identical hardware and configurations. SurrealDB 3.x shows substantial performance gains, especially in CRUD operations and full-table scans. The tests emphasize full durability, providing a realistic comparison for production use.
Recent comprehensive benchmarks demonstrate that SurrealDB 3.x outperforms Postgres, MongoDB, Neo4j, and Redis in various workloads when configured for full durability, running on identical hardware. These results highlight significant performance gains, especially in CRUD operations and full-table scans, marking a notable advancement for SurrealDB.
The benchmarks were conducted on an AMD Ryzen Threadripper 9970X system with 128 GiB of DDR5 RAM and NVMe storage, using the same open-source benchmarking harness across all databases. Each database was tuned for production-grade durability, enabling fsync and WAL flushes, to reflect real-world deployment conditions. The workloads involved 128 clients executing 48 concurrent queries against datasets with 5 to 15 million rows, including mixed data types and complex queries.
SurrealDB 3.x showed a 164-fold increase in full-table scan performance compared to its previous version, with the latest version reaching 11 ops/sec. CRUD throughput improved by 31% from SurrealDB 2.x, with mean operations per second rising from 107k to 141k. Latency reductions ranged from 27% to 99%, depending on the workload. When compared to other databases, SurrealDB demonstrated faster write operations than Postgres and MySQL, with 1.5× and 5-7× higher throughput respectively. In document-oriented workloads, SurrealDB was approximately 1.3× faster than MongoDB in reads and significantly outperformed in unindexed filter scans, being roughly 2.7× faster.
Why It Matters
This benchmarking effort provides a realistic, production-oriented comparison of SurrealDB 3.x against established databases, emphasizing its competitive performance in durability-focused environments. The substantial improvements in query speed and throughput suggest SurrealDB is a viable alternative for multi-model, transactional workloads, especially where full durability and high concurrency are required. These results could influence deployment decisions in enterprise and high-demand applications.

Background
Previous benchmarks with fsync disabled showed faster results but did not reflect typical production conditions. This latest round emphasizes full durability, aligning with real-world deployment scenarios where data integrity is critical. SurrealDB’s latest internal architecture overhaul—covering query parsing, storage, and indexing—has driven the performance gains. Historically, databases like Postgres and MongoDB have been benchmarks for relational and document models, respectively, but SurrealDB’s multi-model approach and recent optimizations position it as a competitive alternative.
