    Server Description

    A memory-optimized virtual machine featuring high RAM density and local SSD storage for memory-intensive, compute-moderate workloads.

    Memory OptimizedStorage & Database

    The Microsoft Azure E16-4as_v4 is a memory-optimized virtual machine from the EASv4 family, featuring an AMD EPYC 7452 processor with 4 dedicated vCPUs across 2 physical cores. Operating at 3.35 GHz on the x86_64 architecture, it is configured with 128.0 GB of RAM and 262 GB of local SSD storage. Benchmark results show a distinct trade-off: while CPU-bound performance is limited, with stress-ng and Passmark CPU scores in the bottom tiers, memory performance remains average, as evidenced by a 45.48 GB/sec large-block read bandwidth and a stable Passmark memory score. This resource profile offers high memory density relative to compute capacity, making it qualitatively cost-effective for memory-heavy, CPU-light applications. It is best suited for in-memory databases, caching layers, and data-intensive workloads requiring a large memory footprint without heavy computational demands.

    Workload Profiles

    0.27Score
    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.
