    CPU and System Topology

    Server Description

    An Intel-powered virtual machine featuring high-speed local NVMe storage and a balanced memory-to-core ratio for localized database workloads.

    Storage & DatabaseMemory Optimized

    Microsoft Azure L4s_v4 is an x86_64 virtual machine from the Lsv4 family, powered by a dedicated 4.2 GHz Intel Xeon 8573C processor. It features 4 vCPUs, 32.0 GB of RAM, and a bundled 960 GB NVMe SSD. Operating on the Microsoft Hyper-V hypervisor, this instance delivers strong single-core performance, highlighted by a Geekbench single-core score of 2158.0 and fast single-threaded gzip compression. However, it exhibits weaker multi-core scaling and constrained memory bandwidth, with large-block reads at 36.35 GB/sec. The high memory-to-vCPU ratio and fast local storage provide qualitative cost efficiency for localized data caching and small database workloads. It is best suited for database operations, single-threaded processing, and web serving.

    Workload Profiles

    0.49Score
    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.
