    Server Description

    A legacy compute-optimized instance featuring dedicated Intel Xeon processors and local NVMe SSD storage for basic workloads.

    Compute OptimizedGeneral Purpose

    Amazon Web Services c3.large is a legacy compute-optimized instance utilizing the Xen hypervisor and an Intel Xeon E5-2680 v2 processor. Operating on an i386 architecture, it provides 2 dedicated vCPUs from a single physical core, 4.0 GB of system memory, and 32 GB of local NVMe SSD storage. Benchmark results indicate limited processing capabilities, with stress-ng and Geekbench scores falling into the bottom decile of cloud servers. Memory bandwidth is also constrained, with large block read speeds of 13.06 GB/sec. Given these performance characteristics and its older hardware profile, the c3.large is best reserved for basic web serving, lightweight background processes, and legacy applications that require dedicated CPU allocation but do not demand high memory throughput or modern instruction sets.

    Workload Profiles

    0.109Score
    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.
