    CPU and System Topology

    Server Description

    A high-capacity memory-optimized instance featuring nearly four terabytes of RAM and local storage for demanding database workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure M128-64ms is a memory-optimized virtual machine designed for memory-intensive enterprise workloads. Powered by a dedicated Intel Xeon 8280L processor, it provides 64 vCPUs (32 physical cores) running at 2.7 GHz on the x86_64 architecture. The server is equipped with an exceptionally large memory capacity of 3892.0 GB (approximately 60.81 GB per core) and 4194 GB of local storage, with no integrated GPUs. While single-core benchmark performance is relatively weak, falling in the bottom 10%, the instance delivers strong large-block memory read and write bandwidth in the top 25%, alongside average multi-core CPU and database performance. This hardware profile makes the M128-64ms highly cost-efficient for memory-bound applications rather than raw single-threaded compute. It is best suited for large-scale databases, in-memory data stores, and heavy caching workloads.

    Workload Profiles

    1.92Score
    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.
