    CPU and System Topology

    Server Description

    A memory-optimized server featuring dedicated AMD EPYC cores, high-density RAM, and fast NVMe storage for memory-intensive workloads.

    Memory OptimizedStorage & Database

    OVHcloud r3-128 is a memory-optimized server instance featuring 16 dedicated physical cores powered by an AMD EPYC processor running at 2.3 GHz. Built on the KVM hypervisor, it provides 128.0 GB of RAM, resulting in a high memory-to-core ratio of 8.0 GB per core. The instance includes a bundled 400 GB NVMe SSD and a baseline network bandwidth of 4 Gbps. Performance benchmarks highlight a top-tier PassMark memory score in the top 10% and strong large-block memory bandwidth in the top 25%. Single-core CPU performance is also strong, though multi-core CPU metrics sit in the average range. Lacking hyperthreading, the dedicated cores deliver predictable execution. This hardware profile is suited for memory-intensive workloads, including database operations, caching layers, and text processing tasks.

    Workload Profiles

    1.3Score
    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.
