    Server Description

    A memory-optimized instance featuring dedicated Intel Xeon processors, high-speed DDR4 RAM, and integrated local NVMe SSD storage.

    Memory OptimizedStorage & Database

    Amazon Web Services r5dn.2xlarge is a memory-optimized instance featuring 8 vCPUs, 4 physical cores, and 64.0 GB of DDR4 RAM powered by an Intel Xeon 8259CL processor at 3.1 GHz. Built on the Nitro hypervisor, it includes a 300 GB local NVMe SSD and offers a baseline network bandwidth of 8 Gbps. Benchmarks show average multi-core CPU and memory bandwidth performance, though single-core execution and database operations are relatively weak. This instance is qualitatively cost-efficient for memory-intensive workloads requiring fast local storage, such as in-memory databases, caching layers, and search indexes, but is less suited for compute-heavy tasks or large-scale LLM inference.

    Workload Profiles

    0.422Score
    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.
