    Server Description

    An ultra-high memory-to-core virtual machine featuring dedicated high-frequency Intel Xeon processing and substantial local storage for memory-intensive workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure FX16-4mds_v2 is a memory-optimized virtual machine from the FXmdsv2 family, built on the Microsoft Hyper-V hypervisor. It features a dedicated Intel Xeon 8573C x86_64 processor running at 4.2 GHz with 4 vCPUs, 2 physical cores, and a 260 MB L3 cache. The server is characterized by an exceptionally high memory capacity of 336.0 GB (84.0 GB per core) and includes 945 GB of local storage with Premium Storage capability. Benchmark data highlights top-tier single-core performance, with a Geekbench single-core score of 2357.0 and strong single-threaded compression speeds. However, multi-core and uncached memory bandwidth benchmarks are comparatively weak due to the low core count. This hardware profile is highly suited for memory-intensive, low-vCPU workloads such as database operations, Redis caching, and memory-heavy single-threaded applications, offering a specialized trade-off between massive RAM capacity and moderate parallel compute.

    Workload Profiles

    0.516Score
    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.
