    Server Description

    A memory-optimized platform featuring high-capacity local NVMe storage and dedicated Intel Xeon processing for demanding database workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r6id.16xlarge is a memory-optimized instance featuring 64 vCPUs (32 physical cores) powered by an Intel Xeon 8375C processor running at 3.5 GHz. It is equipped with 512 GB of DDR4 memory, 3,800 GB of local NVMe SSD storage, and a 25 Gbps baseline network connection. Operating on the AWS Nitro hypervisor, this instance excels in multi-core processing, database operations, and cryptographic tasks, as evidenced by strong benchmark results in PassMark and multi-threaded decompression. The 1:8 vCPU-to-RAM ratio combined with high-capacity local instance storage makes it highly cost-efficient for memory-intensive workloads that require low-latency disk access. It is best suited for hosting large relational databases, in-memory data stores, and intensive data processing pipelines.

    Workload Profiles

    2.7Score
    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.
