    Server Description

    An x86_64 virtual machine featuring a high memory-to-vCPU ratio and local storage for memory-intensive, low-compute workloads.

    Memory OptimizedGeneral Purpose

    Microsoft Azure E4s_v3 is a memory-optimized virtual machine featuring 4 vCPUs and 32.0 GB of RAM, powered by an Intel Xeon 8171M processor at 2.6 GHz. Built on the x86_64 architecture with Microsoft Hyper-V virtualization, it includes 2 physical cores, a 35 MB L3 cache, and a 66 GB local storage disk. Performance benchmarks place this instance in the lower tiers, with stress-ng CPU and memory bandwidth tests scoring in the bottom 10% to 25%. The high 8.0 GB memory-per-vCPU ratio offers qualitative cost efficiency for memory-heavy, compute-light workloads, though it faces performance tradeoffs in processing-intensive tasks. It is suited for small database operations, caching, and memory-bound enterprise applications.

    Workload Profiles

    0.202Score
    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.
