    CPU and System Topology

    Server Description

    An ultra-high-density memory instance featuring nearly four terabytes of RAM and bundled local SSD storage for massive database workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure M128-32ms is a memory-optimized virtual machine designed for memory-intensive workloads. Powered by an Intel Xeon 8280L processor with 32 dedicated vCPUs and 16 physical cores, it features an exceptional 3892.0 GB of RAM and a bundled 4194 GB local SSD. While single-core CPU performance is limited, placing in the bottom 10% in benchmarks, the server delivers strong large-block memory write bandwidth in the top 25% and average multi-core performance. This hardware profile makes it highly efficient for massive in-memory databases, caching layers, and enterprise database systems requiring extreme memory density.

    Workload Profiles

    1.1Score
    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.
