    CPU and System Topology

    Server Description

    A dedicated AMD-powered server combining 128 GB of memory with over 11 TB of local storage for data-intensive workloads.

    Storage & DatabaseMemory Optimized

    Microsoft Azure L16aos_v4 is an x86_64 server from the Laosv4 family, configured with 16 dedicated vCPUs via an AMD EPYC 9V74 processor running at 3.7 GHz. It features 128.0 GB of RAM and a substantial 11519 GB of local storage with Premium Storage capabilities. Operating under Microsoft Hyper-V, the server demonstrates strong single-core capabilities, scoring in the top 25 percent for stress-ng single-core and Geekbench single-core tests, alongside top-tier text processing performance. However, it exhibits a bottleneck in uncached large-block read memory bandwidth, which registers in the bottom 25 percent at 36.77 GB/sec. Given its high storage density and 1 to 8 memory-to-vCPU ratio, the L16aos_v4 is well-suited for storage-heavy workloads, database operations, and text processing applications that benefit from massive local storage and dedicated compute resources.

    Workload Profiles

    0.897Score
    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.
