    Server Description

    A legacy memory-optimized instance featuring dedicated vCPUs, 15 GB of RAM, and local NVMe storage for basic caching workloads.

    Memory OptimizedStorage & Database

    Amazon Web Services r3.large is a memory-optimized, third-generation server instance running on the Xen hypervisor. It features an Intel Xeon E5-2670 v2 processor with 2 dedicated vCPUs (1 physical core, 2 threads) clocked at 2.5 GHz, paired with 15.0 GB of RAM and a 32 GB NVMe SSD. Designed for memory-heavy workloads, its performance benchmarks are generally modest, with stress-ng single-core and multi-core scores falling in the bottom 25% and 10% respectively. Memory bandwidth is also limited, with large block write speeds at 11.51 GB/sec. Lacking AVX-512 support and featuring a 0 Gbps baseline network bandwidth, this instance is best suited for legacy memory-intensive applications, small database operations, or basic caching layers where memory capacity is more critical than high-speed computing or rapid network throughput.

    Workload Profiles

    0.12Score
    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.
