      CPU and System Topology

      Server Description

      A high-frequency, memory-intensive virtual machine delivering exceptional single-core performance and massive memory capacity for specialized, low-concurrency workloads.

      Memory OptimizedCompute Optimized

      The Microsoft Azure FX4-2ms_v2 is a memory-optimized virtual machine from the FXmsv2 family, running on Microsoft Hyper-V. Powered by an x86_64 Intel Xeon 8573C processor operating at 4.2 GHz, it features 1 physical core (2 vCPUs) and a substantial 260 MB L3 cache. The server is provisioned with 84.0 GB of RAM, offering an exceptional 42.0 GB of memory per core, but contains no local storage. Benchmarks highlight outstanding single-core performance, including top-tier Geekbench single-core results and strong single-threaded compression speeds, contrasted by weak multi-core and memory bandwidth performance due to the low core count. This configuration is qualitatively cost-efficient for memory-heavy, single-threaded workloads, making it an appropriate fit for specialized in-memory databases, legacy applications requiring high clock speeds, and low-concurrency data processing tasks.

      Workload Profiles

      0.3Score
      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.
