    Server Description

    A balanced sixty-four vCPU virtual machine featuring local SSD storage, strong multi-core processing, and top-tier memory benchmark performance.

    General PurposeStorage & Database

    Microsoft Azure D64a_v4 is a general-purpose virtual machine from the DAv4 family, utilizing an AMD EPYC 7452 processor with 64 dedicated vCPUs, 32 physical cores, and 256.0 GB of RAM. It includes a 1638 GB local SSD and lacks dedicated GPU accelerators. Benchmark data highlights a clear performance tradeoff: single-core CPU performance is poor, ranking in the bottom 10%, whereas multi-core and memory performance are highly competitive. Specifically, its PassMark memory score ranks in the top 10%, and Geekbench multi-core, PassMark CPU, and multi-threaded bzip3 decompression scores place in the top 25%. This resource configuration provides qualitative cost efficiency for parallelized workloads. The server is suited for database operations, multi-threaded data processing, image processing, and small-scale language model inference.

    Workload Profiles

    2.1Score
    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.
