    CPU and System Topology

    Server Description

    A dedicated four-core virtual server with balanced memory and local SSD storage for predictable, baseline utility workloads.

    General Purpose

    OVHcloud b2-15 is a general-purpose virtual server instance configured with 4 dedicated vCPUs on an Intel Haswell x86_64 architecture running at 2.0 GHz. It features 15.0 GB of RAM, 100 GB of local SSD storage, and operates on the KVM hypervisor. Lacking Hyper-Threading, the instance provides exactly one thread per physical core. Benchmark data indicates that while raw compute and multi-threaded performance fall into the lower 25% tier, memory-bound operations, including Redis SET transactions and database operations, perform at an average level. This resource profile makes the b2-15 a qualitatively cost-effective option for workloads requiring dedicated CPU allocation without the need for high-performance computing. It is best suited for lightweight database hosting, text processing, and general-purpose utility workloads.

    Workload Profiles

    0.327Score
    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.
