    Server Description

    A high-density memory-optimized instance featuring fast local NVMe storage and exceptional single-core processing performance for demanding database workloads.

    Memory OptimizedStorage & Database

    Microsoft Azure FX12-6mds_v2 is a memory-optimized virtual machine powered by an Intel Xeon 8573C processor running at 4.2 GHz on the x86_64 architecture. It features 3 physical cores, 6 vCPUs, and a substantial 252.0 GB of RAM, providing 42.0 GB of memory per core. Local storage is supported by a 945 GB NVMe SSD, and the instance is Premium Storage capable. Benchmark results highlight top-tier single-core and text processing performance, alongside strong single-threaded compression and decompression speeds. Multi-core performance and memory bandwidth fall within average ranges. Given its high memory density and fast local storage, this server is well-suited for memory-intensive databases, text processing workloads, and data compression tasks.

    Workload Profiles

    0.74Score
    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.
