    CPU and System Topology

    Server Description

    A dedicated general-purpose instance offering balanced memory performance and local SSD storage for lightweight database and utility workloads.

    General Purpose

    The OVHcloud b2-15 is a general-purpose virtual server featuring 4 dedicated x86_64 physical cores powered by an Intel Haswell processor running at 2.0 GHz. It is equipped with 15.0 GB of RAM, a 100 GB local SSD, and a baseline network bandwidth of 0 Gbps. Operating on the KVM hypervisor, this instance delivers dedicated CPU allocation but relies on older hardware architecture. Benchmark results show weak to poor CPU compute performance, though memory-bound tasks, Redis SET operations, and database operations achieve average tier results. Lacking modern instruction sets like AVX-512, the b2-15 is not suited for intensive mathematical or large-scale AI workloads. Instead, it represents a cost-efficient option for general-purpose tasks, lightweight database management, text processing, and basic web serving where dedicated resources are preferred over shared-core alternatives.

    Workload Profiles

    0.33Score
    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.
