    CPU and System Topology

    Server Description

    A high-density, memory-optimized platform featuring massive RAM capacity and strong multi-threaded performance for enterprise database workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure M128ms is a memory-intensive virtual machine in the MS family, featuring 128 dedicated vCPUs and 3892.0 GB of RAM. Powered by Intel Xeon 8280M processors at 2.7 GHz, it provides 64 physical cores and 4194 GB of local SSD storage. The server exhibits a distinct performance profile: single-core benchmarks, such as Geekbench single-core, rank in the bottom 10%, whereas multi-core and memory bandwidth tests perform in the top 25% and top 10% respectively. Uncached large-block read memory bandwidth reaches 375.19 GB/sec. This server is highly optimized for memory-heavy workloads, including large in-memory databases and Redis caching layers, where it handles 79.29 million SET operations per second. However, it is less efficient for single-threaded processing or LLM text generation.

    Workload Profiles

    3.1Score
    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.
