    Server Description

    A balanced general-purpose platform featuring high-speed local NVMe storage and 50 Gbps networking for data-intensive multi-threaded workloads.

    General PurposeStorage & Database

    Amazon Web Services m5dn.12xlarge is a general-purpose instance built on the Nitro hypervisor, featuring an Intel Xeon 8259CL processor with 48 vCPUs, 24 physical cores, and 192 GB of DDR4 memory. It includes 1800 GB of local NVMe SSD storage and a 50 Gbps baseline network bandwidth. Benchmarks show average multi-core performance, memory bandwidth, and database operations, though single-core execution and single-threaded compression fall into the lower tier. The instance offers a balanced resource profile, making it qualitatively cost-effective for workloads requiring high network throughput and local storage without needing top-tier single-thread compute. It is well-suited for database operations, caching layers, static web serving, and multi-threaded data processing.

    Workload Profiles

    1.6Score
    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.
