    CPU and System Topology

    Server Description

    A memory-intensive virtual server featuring massive RAM capacity and local SSD storage, optimized for large-scale database and caching workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure M64ms is a memory-optimized virtual machine built on the Microsoft Hyper-V hypervisor. It features 64 dedicated vCPUs powered by an Intel Xeon 8280L processor running at 2.7 GHz, paired with 1792.0 GB of RAM and 2097 GB of local SSD storage. While single-core CPU benchmarks place this instance in the bottom 10%, its multi-core performance and memory bandwidth are robust. Notably, uncached large-block read memory bandwidth reaches a strong 196.25 GB/sec. This high memory-to-vCPU ratio makes the M64ms highly cost-efficient for memory-intensive enterprise workloads. It is best suited for large in-memory databases, data caching layers, and heavy relational database management systems where memory capacity is the primary bottleneck rather than single-threaded compute speed.

    Performance

    Workload Profiles

    1.7Score
    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.
