    Server Description

    A memory-optimized platform featuring dedicated Intel Xeon processors, high-speed DDR4 RAM, and integrated NVMe SSD local storage for demanding database workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r6id.4xlarge is a memory-optimized instance featuring 16 vCPUs and 128.0 GB of DDR4 RAM, powered by an Intel Xeon 8375C processor running at 3.5 GHz. Built on the AWS Nitro hypervisor, it includes a bundled 950 GB NVMe SSD local instance store and offers a baseline network bandwidth of 6 Gbps. Benchmark data shows average tier performance, with a multi-core stress-ng score of 15466.97 and a Redis SET throughput of 15.88 million operations per second. While it lacks GPU acceleration and shows weaker performance on larger LLM inference tasks, its high memory-to-vCPU ratio and fast local storage provide strong resource density. This configuration is well-suited for memory-intensive applications, database operations, and caching workloads.

    Workload Profiles

    1Score
    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.
