    Server Description

    A memory-optimized instance featuring dedicated Intel Xeon processing, an 8:1 RAM-to-vCPU ratio, and integrated local NVMe SSD storage.

    Memory OptimizedStorage & Database

    Amazon Web Services r6idn.large is a memory-optimized instance featuring 2 vCPUs from a single physical Intel Xeon 8375C core running at 3.5 GHz. It includes 16.0 GB of DDR4 RAM, a 118 GB local NVMe SSD, and a 3 Gbps baseline network speed. Operating on the Nitro hypervisor, this x86_64 instance delivers average single-core CPU performance but exhibits limited multi-core scaling and memory bandwidth, with benchmarks in these areas falling into the bottom 10%. The hardware profile is suited for memory-intensive applications with low parallel processing demands, such as small databases or caching systems.

    Workload Profiles

    0.207Score
    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.
