    Server Description

    An ARM-based storage-optimized instance delivering massive local NVMe capacity and strong multi-core performance for intensive database and caching workloads.

    Storage & DatabaseMemory Optimized

    Amazon Web Services i4g.16xlarge is a storage-optimized server featuring 64 dedicated physical ARMv8 cores via the AWS Graviton Neoverse-N1 processor running at 2.5 GHz. It is equipped with 512.0 GB of RAM, 15,000 GB of local NVMe SSD storage, and a 38 Gbps baseline network interface. Operating on the Nitro hypervisor, this instance delivers strong multi-core CPU performance and high cached memory bandwidth, alongside exceptional Redis SET throughput of 72.23 million operations per second and static web serving speeds of 45.46 GB/sec. However, single-core processing and LLM text generation represent performance tradeoffs. This server is highly efficient for large-scale database operations, caching layers, and high-throughput web serving workloads requiring dense local storage.

    Workload Profiles

    2.3Score
    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.
