    Server Description

    An ARM64 storage-optimized instance featuring a high-capacity local NVMe SSD and a balanced memory-to-vCPU ratio for storage-intensive applications.

    Storage & DatabaseMemory Optimized

    Amazon Web Services is4gen.large is an ARM64 storage-optimized server utilizing the Nitro hypervisor and an AWS Graviton Neoverse-N1 processor. It features 2 dedicated physical cores at 2.5 GHz, 12.0 GB of RAM, and a 1875 GB local NVMe SSD. While the instance offers a high storage-to-vCPU ratio, benchmarks show modest compute and memory performance, with a weak stress-ng multi-core score of 3013.58 and a poor Geekbench multi-core score of 1753.0. Memory bandwidth is also limited, with large block read speeds at 37.37 GB/sec. This hardware profile is qualitatively cost-efficient for storage-heavy workloads requiring high local capacity but low computational intensity, such as lightweight database hosting and file serving.

    Workload Profiles

    0.19Score
    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.
