    Server Description

    A memory-optimized instance featuring local NVMe SSD storage and enhanced networking for data-intensive workloads requiring high memory-to-CPU ratios.

    Memory OptimizedStorage & Database

    The Amazon Web Services r5dn.2xlarge is a memory-optimized instance utilizing the Nitro hypervisor and an x86_64 Intel Xeon 8259CL processor. It features 8 vCPUs, 64.0 GB of DDR4 memory, and 300 GB of local NVMe SSD storage. Optimized for network and EBS performance, it provides an 8 Gbps baseline network bandwidth. Benchmark data shows average multi-core CPU and memory bandwidth performance, though single-core execution and database operations trend toward the lower tiers. This instance is designed for memory-intensive workloads that require local high-speed storage, such as caching layers, in-memory databases, and data processing tasks where memory capacity and network throughput are more critical than high single-core compute performance. Qualitatively, it offers high resource density for memory-bound applications requiring local SSD caching.

    Workload Profiles

    0.421Score
    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.
