      CPU and System Topology

      Server Description

      An ARM-powered, memory-optimized virtual machine featuring a high memory-to-core ratio for efficient database and caching workloads.

      Memory OptimizedGeneral Purpose

      Microsoft Azure E4ps_v6 is an ARM-based virtual machine from the Epsv6 family, powered by a 3.4 GHz Microsoft ARM Neoverse-N2 processor with 4 dedicated physical cores and 32.0 GB of RAM. Running on Microsoft Hyper-V, this memory-optimized instance lacks local storage but supports Premium Storage. Benchmarks indicate average overall compute performance, with a stress-ng multi-core score of 8269.76 and a strong single-threaded gzip compression rate of 33.04 GB/sec. Memory subsystem performance is robust, highlighted by a strong PassMark memory score and 454.17 GB/sec cached read bandwidth. However, cryptographic operations represent a performance bottleneck, with a poor PassMark encryption score of 750.01. The 1:8 vCPU-to-RAM ratio makes this server highly efficient for memory-intensive workloads such as database operations, Redis caching, and web serving, where high memory density is required without excessive compute overhead.

      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.
