    CPU and System Topology

    Server Description

    A memory-heavy virtual machine featuring an exceptional memory-to-core ratio and local storage for memory-intensive database and caching workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure GS5-8 is an x86_64 memory-optimized virtual machine powered by an Intel Xeon E5-2698B v3 processor running at 2.0 GHz on Microsoft Hyper-V. It features 8 dedicated physical cores paired with 448.0 GB of RAM, providing an exceptionally high memory-to-vCPU ratio of 56.0 GB per core. The instance includes 918 GB of local storage but lacks complimentary public IPv4 addresses. Performance benchmarks indicate a tradeoff: single-core CPU performance is poor, ranking in the bottom 10% for stress-ng, while multi-core performance and memory bandwidth remain in the average tier. This hardware profile is qualitatively cost-efficient for memory-bound applications rather than compute-heavy tasks. It is best suited for in-memory databases, caching layers, and database operations that leverage its massive memory footprint and local storage.

    Workload Profiles

    0.55Score
    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.
