    CPU and System Topology

    Server Description

    A high-frequency, memory-intensive virtual machine featuring exceptional single-core performance and dense memory-to-core allocation for specialized database workloads.

    Memory OptimizedStorage & Database

    The Microsoft Azure FX4mds_v2 is a memory-optimized virtual machine from the FXmdsv2 family, powered by a 4.2 GHz Intel Xeon 8573C processor. It features 4 dedicated vCPUs (2 physical cores) and a substantial 84.0 GB of RAM, providing an exceptional 21.0 GB of memory per core. The server includes 236 GB of local storage and supports Premium Storage. Benchmarks reveal outstanding single-core performance, with a top-tier Geekbench single-core score of 2262.0 and strong single-threaded compression speeds. However, its multi-core and uncached memory bandwidth performance are relatively weak due to the 2-core physical limit. This configuration is highly cost-efficient for memory-heavy, single-thread-bound workloads such as databases, caching layers, and memory-intensive enterprise applications, while being less suited for highly parallelized computing tasks.

    Workload Profiles

    0.538Score
    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.
