      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring a high memory-to-core ratio and strong single-threaded performance for memory-bound enterprise workloads.

      Memory Optimized

      Microsoft Azure E16-4s_v6 is a memory-optimized x86_64 server instance from the Esv6 family, powered by a 4.2 GHz Intel Xeon 8573C processor. It features 4 dedicated vCPUs and a substantial 128.0 GB of RAM, providing 32.0 GB of memory per core. The instance lacks local storage and GPUs but supports Premium Storage. Benchmark data reveals strong single-core performance, highlighted by a Geekbench single-core score of 2126.0 and high single-threaded gzip compression speeds. Conversely, multi-core and memory bandwidth benchmarks are relatively weak, with uncached large-block read speeds at 34.79 GB/sec. Given its high memory-to-vCPU ratio and dedicated CPU allocation, this instance is qualitatively cost-effective for memory-intensive workloads that do not demand high parallel compute scaling. It is highly suited for in-memory caching, lightweight database operations, and memory-bound enterprise applications.

      Workload Profiles

      0.5Score
      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.
