    Server Description

    A dedicated four-core x86_64 virtual machine featuring a generous memory-to-vCPU ratio and integrated local storage for memory-centric workloads.

    General PurposeMemory Optimized

    Microsoft Azure D12 is a D-family virtual machine featuring 4 dedicated vCPUs powered by an Intel Xeon 8171M processor running at 2.6 GHz on the x86_64 architecture. Virtualized via Microsoft Hyper-V, it is equipped with 28.0 GB of RAM and 205 GB of local storage, with no GPU capabilities. Benchmark data shows weak CPU performance, with stress-ng and Geekbench scores falling in the bottom 25% and bottom 10% respectively. However, memory bandwidth and PassMark memory scores remain average, and Redis SET operations reach 5.98 million operations per second. The instance presents a clear tradeoff: lower compute performance paired with a relatively high memory-to-core ratio. This configuration provides qualitative cost efficiency for memory-sensitive but compute-light applications. It is best suited for general-purpose workloads, caching layers, and database operations that benefit from its 28.0 GB memory capacity rather than raw processing power.

    Workload Profiles

    0.36Score
    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.
