    Server Description

    A high memory virtual machine with exceptional memory capacity per core and strong single core performance for intensive database workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure FX8-4ms_v2 is a memory-optimized virtual machine from the FXmsv2 family, designed for memory-intensive workloads. Running on the Microsoft Hyper-V hypervisor, it features an Intel Xeon 8573C processor with 4 dedicated vCPUs, 2 physical cores, and a high clock speed of 4.2 GHz. The instance is equipped with 168.0 GB of RAM, yielding an exceptional 42.0 GB of memory per core, alongside a large 260 MB L3 cache. While it lacks local storage and GPUs, it supports Premium Storage. Benchmarks show top-tier single-core performance, including strong single-threaded compression and text processing, though multi-core scaling and large-block memory bandwidth are relatively weak. This hardware profile is highly effective for in-memory databases, caching layers, and memory-heavy, single-threaded applications.

    Workload Profiles

    0.541Score
    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.
