    Server Description

    A memory-intensive virtual machine featuring massive RAM capacity, large local SSD storage, and exceptional multi-core memory bandwidth for parallel workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure M128m is a memory-intensive virtual machine from the MS family, utilizing the Microsoft Hyper-V hypervisor. It features an Intel Xeon 8280M processor with 128 dedicated vCPUs across 64 physical cores, operating at 2.7 GHz. The server is equipped with 3892.0 GB of RAM, yielding 30.41 GB per core, and includes 14680 GB of local SSD storage. While single-core benchmarks and single-threaded compression tasks rank in the bottom 10%, multi-core performance and memory bandwidth are highly competitive. Large-block uncached read memory bandwidth reaches 382.78 GB/sec, placing it in the top 10%. This hardware profile is optimized for memory-heavy workloads, such as large-scale in-memory databases, Redis deployments, and multi-threaded data processing, where massive memory capacity and high parallel throughput outweigh single-thread execution speeds.

    Workload Profiles

    3Score
    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.
