    CPU and System Topology

    Server Description

    A compute-optimized virtual machine featuring high-frequency Intel Xeon processors and a low memory-to-CPU ratio for single-threaded workloads.

    Compute OptimizedGeneral Purpose

    Microsoft Azure D4ls_v6 is a compute-optimized virtual machine from the Dlsv6 family, featuring 4 dedicated vCPUs across 2 physical Intel Xeon 8573C cores running at 4.2 GHz. Built on the x86_64 architecture, it provides 8.0 GB of system memory, resulting in a 1:2 vCPU-to-RAM ratio. The instance contains no local storage or GPU accelerators but supports Premium Storage. Benchmarks indicate strong single-core capabilities, with a Geekbench single-core score of 2115.0 and high single-threaded gzip compression throughput. Conversely, multi-core and memory bandwidth metrics are relatively weak, as shown by a PassMark memory score of 1647.88. This configuration is qualitatively cost-effective for compute-heavy, low-memory workloads such as text processing, single-threaded applications, and lightweight web serving, while being less suitable for memory-intensive databases or complex multi-threaded operations.

    Workload Profiles

    0.478Score
    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.
