    Server Description

    A memory-optimized instance featuring dedicated Intel Xeon processors, local NVMe SSD storage, and a high memory-to-vCPU ratio for data-intensive workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r5dn.2xlarge is an x86_64 memory-optimized instance running on the Nitro hypervisor. It is equipped with an Intel Xeon 8259CL processor running at 3.1 GHz, offering 8 vCPUs, 4 physical cores, and 64.0 GB of DDR4 RAM. Local storage consists of a 300 GB NVMe SSD, complemented by an 8 Gbps baseline network bandwidth. Performance benchmarks show average multi-core capabilities, with a stress-ng multi-core score of 6870.73 and average memory read bandwidth of 51.32 GB/sec for large blocks. However, single-core performance is weak, as evidenced by a Geekbench single-core score of 1155.0. Qualitatively, the instance provides high memory density and local storage at the expense of raw single-threaded compute power. It is suited for memory-intensive workloads, caching layers, and database operations that leverage its 1:8 vCPU-to-RAM ratio and local NVMe storage.

    Workload Profiles

    0.43Score
    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.
