    Server Description

    A memory-optimized instance featuring dedicated Intel Xeon processors, 32 GB of DDR4 RAM, and local NVMe SSD storage.

    Memory OptimizedStorage & Database

    Amazon Web Services r5dn.xlarge is a memory-optimized instance featuring 4 vCPUs and 32.0 GB of DDR4 memory. Built on the Nitro hypervisor, it includes 150 GB of local NVMe SSD storage and a baseline network bandwidth of 4 Gbps. While its memory capacity is high, benchmark data shows weak CPU and memory bandwidth performance, with stress-ng, Geekbench, and PassMark CPU scores falling into the bottom 25%. However, its PassMark memory score achieves an average rating. This instance is designed for memory-intensive workloads with moderate compute requirements, such as database operations and caching layers.

    Workload Profiles

    0.257Score
    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.
