The cloud isn’t just about scaling—it’s about optimizing. As more enterprises turn to PostgreSQL to power mission-critical applications, the performance of cloud storage becomes a make-or-break factor. But here’s the catch: achieving consistent, low-latency performance on public cloud block storage often comes with eye-watering costs, unpredictable variability, and rigid provisioning.
That’s exactly the problem Volumez set out to solve—and according to a new independent benchmarking report from Architecting IT the results are game-changing.
Volumez + OCI: Enterprise-grade PostgreSQL at unbeatable economics
The report tested PostgreSQL performance across AWS, Azure, and Oracle Cloud Infrastructure (OCI) using the industry-standard pgbench tool. The findings? Volumez consistently outperformed native cloud block storage in all environments—while delivering massive cost savings, lower latency, and more predictable throughput.
But the standout winner was Oracle Cloud Infrastructure. Volumez on OCI delivered:
- Lowest latency across all cloud platforms
- Highest throughput under real-world PostgreSQL workloads
- Up to 80% cost savings compared to native high-performance storage on AWS (like io2 Block Express)
This isn’t a synthetic lab test—it’s production-realistic benchmarking, showing how PostgreSQL actually behaves under load when powered by smart infrastructure.



Why it works: The purpose-built data path
Volumez delivers Data Infrastructure as a Service (DIaaS), orchestrating local NVMe storage into a high-performance, resilient storage plane. Unlike traditional solutions, Volumez:
- Decouples performance from capacity, eliminating costly over-provisioning
- Optimizes IOPS and bandwidth across volumes, enabling flexible, policy-driven resource allocation
- Delivers sub-millisecond latency via NVMe-over-TCP—without inserting itself into the I/O path
And on OCI, that architecture gets an extra boost. Oracle’s non-blocking, non-oversubscribed infrastructure complements Volumez’s intelligent orchestration, resulting in highly deterministic I/O and outstanding price/performance.
Benchmark takeaways: More performance, more savings
The bottom line? For any organization running PostgreSQL in the cloud, Volumez on OCI for PostgreSQL is the new performance-cost leader. Because of the cost/performance economics we enable on OCI, Volumez has created a specific market-place offer in OCI and will be providing the same offer and economics on AWS and Azure.

If you’re scaling PostgreSQL or any other performance-sensitive workload in the cloud, it’s time to take a closer look at how Volumez can save you money, deliver consistent performance, and eliminate the guesswork of IOPS planning.
