    Server Description

    An ARM64 storage-optimized instance featuring high-capacity local NVMe SSDs and balanced multi-core performance for database and web serving workloads.

    Storage & DatabaseGeneral Purpose

    Amazon Web Services im4gn.4xlarge is a storage-optimized instance featuring 16 dedicated ARM64 physical cores on an AWS Neoverse-N1 processor running at 2.5 GHz. It is equipped with 64.0 GB of memory and a substantial 7500 GB of local NVMe SSD storage, supported by a 25 Gbps baseline network speed. Operating on the Nitro hypervisor, the instance delivers balanced multi-core performance, as evidenced by a stress-ng multi-core score of 24284.34 and 18.89 million Redis SET operations per second. While single-threaded performance and encryption benchmarks are relatively weak, its high storage density and solid memory bandwidth make it highly cost-efficient for storage-heavy workloads. The im4gn.4xlarge is best suited for database operations, static web serving, and multi-threaded data processing tasks.

    Workload Profiles

    0.9Score
    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.
