    CPU and System Topology

    Server Description

    A high-density storage and memory virtual machine featuring massive local NVMe SSD capacity and strong multi-core processing performance.

    Storage & DatabaseMemory OptimizedGeneral Purpose

    The Microsoft Azure L64s_v4 is a storage-optimized virtual machine from the Lsv4 family, featuring 64 vCPUs and 512.0 GB of RAM. Powered by an Intel Xeon 8573C processor running at 4.2 GHz, it provides 32 physical cores and a 260 MB L3 cache. The server is equipped with 15,359 GB of local NVMe SSD storage, making it highly capable for data-intensive operations. Benchmark data shows top-tier performance in multi-core processing and static web serving, alongside strong memory bandwidth and database operation speeds. Single-core performance remains average, highlighting a tradeoff where multi-threaded and storage-bound tasks are prioritized. This virtual machine is highly suited for large-scale databases, high-throughput web serving, and memory-intensive caching applications.

    Workload Profiles

    3.7Score
    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.
