    Server Description

    A storage-optimized virtual server featuring dedicated AMD EPYC processors, substantial local storage, and a balanced memory-to-core ratio for database workloads.

    Storage & DatabaseMemory Optimized

    The Microsoft Azure L16as_v4 is a storage-oriented server instance from the Lasv4 family, powered by an AMD EPYC 9V74 processor operating at 3.7 GHz. It features 16 vCPUs, 128.0 GB of RAM, and 3840 GB of local storage with Premium Storage capability. Operating on the x86_64 architecture via Microsoft Hyper-V, this instance delivers strong single-core and text-processing performance, though its multi-core and database operations fall in the average tier. A key performance tradeoff is its uncached large-block read memory bandwidth, which ranks in the bottom 25 percent. With its high local storage capacity and a 1 to 8 vCPU-to-RAM ratio, the L16as_v4 is highly suited for database hosting, caching layers, and storage-intensive applications that benefit from dedicated CPU resources and large local disk capacity without requiring GPU acceleration.

    Workload Profiles

    0.913Score
    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.
