      CPU and System Topology

      Server Description

      A dedicated Intel Xeon compute instance with a low memory-to-core ratio, optimized for single-threaded tasks and light web serving.

      Compute OptimizedGeneral Purpose

      Microsoft Azure D4ls_v6 is an x86_64 server instance in the Dlsv6 family, powered by a 4.2 GHz Intel Xeon 8573C processor. It provides 4 dedicated vCPUs across 2 physical cores, 8.0 GB of RAM, and no local storage. The CPU features a 260 MB L3 cache and supports advanced vector and matrix extensions (AVX-512 and AMX). Performance benchmarks show strong single-core execution, with a Geekbench single-core score of 2115.0 and strong single-threaded gzip compression. However, multi-core performance and memory bandwidth are relatively weak, with large-block memory read bandwidth at 36.43 GB/sec. This low-memory configuration is best suited for workloads with modest memory requirements, such as basic web serving, single-threaded applications, light text processing, and small-scale language model inference.

      Workload Profiles

      0.48Score
      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.
