    Server Description

    A high-bandwidth, memory-optimized server featuring dedicated Intel Xeon processors, local NVMe SSD storage, and 100 Gbps networking for demanding database workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r6idn.16xlarge is a memory-optimized instance featuring 64 vCPUs and 512 GB of DDR4 RAM, powered by an Intel Xeon 8375C processor running at 3.5 GHz. Built on the Nitro hypervisor, this x86_64 server includes 3800 GB of local NVMe SSD storage and a 100 Gbps baseline network bandwidth. Performance benchmarks indicate strong multi-core capabilities, with a stress-ng multi-core score of 61937.6 and a Passmark CPU score of 57772.18. The hardware configuration is highly effective for data-intensive tasks, showing strong results in database operations and static web serving. This instance is well-suited for large-scale databases, memory-intensive enterprise applications, real-time analytics, and CPU-based machine learning inference.

    Workload Profiles

    2.67Score
    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.
