    Server Description

    A memory-optimized architecture combining dedicated Intel Xeon processing with high-speed local NVMe storage for data-intensive workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r6idn.2xlarge is a memory-optimized instance utilizing the Nitro hypervisor and an Intel Xeon 8375C processor. It delivers 8 vCPUs, 64.0 GB of DDR4 RAM, and a bundled 474 GB NVMe SSD instance store. Operating at 3.5 GHz, the CPU supports advanced instruction sets including AVX-512. Benchmark results place the instance in the average tier for most operations, with a Passmark database score of 3957.99 and 7.88 million Redis SET operations per second. However, performance tradeoffs exist, particularly in multi-threaded bzip3 decompression and medium-sized LLM inference, where it scores in the lower percentiles. With its 8:1 memory-to-vCPU ratio and high-speed local storage, this instance is suited for memory-intensive databases, caching layers, and static web serving.

    Workload Profiles

    0.605Score
    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.
