    CPU and System Topology

    Server Description

    A dedicated dual-core virtual server with fifteen gigabytes of memory and local solid-state storage for memory-bound workloads.

    Memory OptimizedGeneral Purpose

    OVHcloud r2-15 is a memory-optimized virtual server running on the KVM hypervisor. It features an x86_64 Intel Haswell processor with 2 dedicated physical cores, 2 vCPUs, and a clock speed of 2.2 GHz. The hardware configuration includes 15.0 GB of RAM, a 50 GB SSD, and one complimentary public IPv4 address. Performance benchmarks place the instance in the lower tier, with a single-core stress-ng score of 1098.99 and a multi-core score of 2095.09. Large block memory read bandwidth is recorded at 22.28 GB/sec, and Redis SET operations reach 3.07 million operations per second. Lacking modern instruction sets like AVX-512, the r2-15 represents a cost-efficient option for memory-bound workloads that do not demand high compute performance. It is best suited for lightweight database hosting, caching layers, and basic web serving.

    Workload Profiles

    0.21Score
    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.
