    Server Description

    A compute-optimized virtual server featuring thirty-two virtual cores and local NVMe storage for multi-threaded legacy workloads.

    Compute OptimizedStorage & Database

    Amazon Web Services c3.8xlarge is a compute-optimized instance featuring 32 vCPUs and 16 physical cores powered by an Intel Xeon E5-2680 v2 processor running at 2.8 GHz. Built on the x86_64 architecture and managed via the Xen hypervisor, it includes 60.0 GB of memory and 640 GB of local NVMe SSD storage. The instance delivers a baseline network bandwidth of 5 Gbps. Benchmark data shows weak single-core performance but average multi-core capabilities, with steady throughput in memory bandwidth, Redis SET operations, and static web serving. Lacking modern instruction sets like AVX-512, this instance is best suited for legacy multi-threaded workloads, software compilation, and database operations where high core density is required without the premium cost of newer hardware generations.

    Workload Profiles

    0.944Score
    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.
