    Server Description

    An x86_64 compute-optimized instance featuring dedicated Intel Xeon cores, bundled local NVMe SSD storage, and balanced multi-core performance.

    Compute OptimizedStorage & Database

    Amazon Web Services c3.4xlarge is a compute-optimized instance featuring 16 vCPUs and 8 physical cores powered by an Intel Xeon E5-2680 v2 processor at 2.8 GHz. It includes 30.0 GB of memory, 320 GB of local NVMe SSD storage, and a 2 Gbps baseline network speed. Running on the Xen hypervisor, this x86_64 instance exhibits a clear performance tradeoff: single-core benchmarks are weak, placing in the bottom 25%, while multi-core performance and memory bandwidth remain in the average tier. Lacking modern instruction sets like AVX-512, it is best suited for legacy multi-threaded applications, static web serving, and software compilation where local NVMe storage is beneficial.

    Workload Profiles

    0.59Score
    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.
