    Server Description

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

    Memory OptimizedStorage & Database

    Amazon Web Services r5d.24xlarge is a memory-optimized instance utilizing the Nitro hypervisor. It features 96 vCPUs and 48 physical cores from an Intel Xeon 8259CL processor running at 3.1 GHz, paired with 768.0 GB of DDR4 memory and 3600 GB of local NVMe SSD storage. The instance delivers strong multi-core CPU performance and high memory bandwidth, though its single-core performance is weak. It achieves strong results in Redis SET operations and static web serving throughput, while LLM text generation speeds remain low. This hardware profile is suited for memory-intensive databases, caching layers, and multi-threaded data processing workloads requiring high-capacity local storage.

    Workload Profiles

    2.9Score
    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.
