    Server Description

    A dedicated x86_64 server featuring 512 GB RAM and 2 TB local storage, optimized for memory-bound, highly parallelized database workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure M64ls is a dedicated virtual machine in the MS family, powered by an Intel Xeon 8280M processor with 64 vCPUs and 32 physical cores. It features 512.0 GB of RAM, 2097 GB of local storage, and is premium storage capable, running on the Microsoft Hyper-V hypervisor. Benchmark data shows a distinct tradeoff: single-core performance is poor, ranking in the bottom 10% for tasks like gzip compression and Geekbench single-core tests. However, multi-core performance and database operations reach average levels, and large-block read-only memory bandwidth is strong, placing in the top 25% at 210.73 GB/sec. Lacking GPU acceleration, this instance is designed for memory-intensive, highly parallelized workloads such as database management, Redis caching, and multi-threaded data processing, where its dedicated resource allocation provides stable execution.

    Workload Profiles

    1.73Score
    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.
