    Server Description

    A memory-optimized x86_64 instance featuring high-capacity DDR4 RAM, fast local NVMe SSD storage, and strong multi-core processing capabilities.

    Memory OptimizedStorage & Database

    Amazon Web Services r6id.16xlarge is a memory-optimized instance featuring 64 vCPUs and 32 physical cores powered by 3.5 GHz Intel Xeon 8375C processors. It is configured with 512.0 GB of DDR4 memory and 3800 GB of local NVMe SSD storage, operating on the Nitro hypervisor with a baseline network bandwidth of 25 Gbps. Benchmark data highlights strong multi-core CPU performance, high database operations throughput, and strong static web serving capabilities, while single-core metrics remain average. The integration of high-capacity RAM and fast local storage provides a resource-dense profile that is highly cost-efficient for workloads requiring rapid data access without external storage overhead. This instance is well-suited for large-scale databases, in-memory caching, and data-intensive enterprise applications.

    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.
