    CPU and System Topology

    Server Description

    A memory-optimized server featuring dedicated AMD EPYC cores and high-speed NVMe storage for demanding database and caching workloads.

    Memory OptimizedStorage & DatabaseCompute Optimized

    OVHcloud r3-256 is a memory-optimized server instance utilizing the KVM hypervisor and powered by an x86_64 AMD EPYC processor. It features 32 dedicated physical cores and 32 vCPUs running at 2.3 GHz, paired with 256.0 GB of RAM and a 400 GB NVMe SSD. The instance delivers 8 Gbps of baseline network bandwidth. In performance benchmarks, the r3-256 excels in multi-core processing and memory bandwidth, scoring in the top 25% for stress-ng multi-core tests and Redis SET operations, which reach 75.95 million operations per second. Its high memory-to-core ratio of 8.0 GB per core makes it highly efficient for memory-intensive workloads without the overhead of hyperthreading. This server is optimized for database hosting, in-memory caching, software compilation, and data-intensive enterprise applications.

    Workload Profiles

    2.1Score
    Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
