    CPU and System Topology

    Server Description

    A dual-vCPU virtual machine combining strong single-core AMD processor performance with 1.4 TB of high-speed local NVMe SSD storage.

    Storage & DatabaseMemory OptimizedGeneral Purpose

    Microsoft Azure L2aos_v4 is a storage and memory-optimized virtual machine from the Laosv4 family, running on the Microsoft Hyper-V hypervisor. It features a dedicated AMD EPYC 9V74 x86_64 processor operating at 3.7 GHz with 2 vCPUs (1 physical core, 2 threads) and 16.0 GB of RAM. A key hardware highlight is its bundled 1440 GB local NVMe SSD storage. Performance benchmarks show strong single-core CPU capabilities, ranking in the top 25% for stress-ng and Geekbench single-core tests. However, multi-core performance, database operations, and small-block read memory bandwidth are weak to poor due to the dual-vCPU constraint. This server is qualitatively cost-efficient for storage-heavy, low-compute workloads, making it suitable for lightweight database hosting, local caching, and single-threaded data processing.

    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.
