      CPU and System Topology

      Server Description

      A low-memory, compute-focused virtual server featuring dedicated high-frequency Intel Xeon processing for single-threaded and lightweight web workloads.

      Compute OptimizedGeneral Purpose

      Microsoft Azure D4ls_v7 is an x86_64 server instance from the Dlsv7 family, configured with 4 vCPUs and 8.0 GB of memory. It features a dedicated Intel Xeon 6973P-C processor operating at 4.2 GHz with 2 physical cores and a 480 MB L3 cache. The instance lacks local storage and integrated GPUs but supports Premium Storage. Performance benchmarks reveal strong single-threaded capabilities, with gzip compression reaching 34.6 GB/sec, though multi-core CPU performance and memory write bandwidth are relatively weak. With a 2.0 GB RAM-per-core ratio, this low-memory instance is qualitatively cost-efficient for compute-focused workloads with minimal memory requirements. It is best suited for lightweight web serving, Redis caching, and single-threaded processing tasks, while remaining constrained for memory-heavy databases or large language model inference.

      Workload Profiles

      0.54Score
      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.
