    CPU and System Topology

    Server Description

    A burstable, budget-friendly virtual machine with moderate memory capacity for handling low-intensity workloads and temporary CPU spikes.

    Burstable & BudgetGeneral Purpose

    Microsoft Azure B2ms is a burstable virtual machine from the BS family, utilizing an Intel Xeon 8272CL processor with 2 vCPUs, 2 physical cores, and 8.0 GB of RAM. Operating on the Microsoft Hyper-V hypervisor, this x86_64 server features a 2.6 GHz clock speed, 16 GB of local storage, and is Premium Storage capable. Performance benchmarks place the instance largely in the bottom 25% tier, with a stress-ng single-core score of 1245.98 and a multi-core score of 2456.99. Memory bandwidth and cryptographic operations also reflect lower-tier performance. Given its burstable CPU allocation and moderate memory-to-core ratio, the B2ms is a cost-effective option for low-traffic web serving, small database operations, and lightweight development tasks that do not require continuous, high-performance compute resources.

    Workload Profiles

    0.2Score
    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.
