      Server Description

      A memory-optimized virtual instance featuring a high RAM-to-vCPU ratio for entry-level database and caching workloads.

      Memory Optimized

      Amazon Web Services r5n.large is a memory-optimized instance running on the Nitro hypervisor. It features an x86_64 Intel Xeon 8259CL processor with 2 vCPUs, 1 physical core, and a clock speed of 3.1 GHz. The instance is configured with 16.0 GB of DDR4 memory, providing a high memory-to-vCPU ratio of 8.0 GB per core, though it lacks local storage and GPU accelerators. Benchmark data indicates modest performance, with a stress-ng multi-core score of 1733.09 and a Passmark memory score of 1660.52. Uncached large-block memory read bandwidth is measured at 13.58 GB/sec. Given its high memory density relative to its processing power, the r5n.large is qualitatively cost-effective for memory-bound workloads that do not require intensive CPU performance. It is suited for lightweight database operations, caching systems, and general-purpose applications requiring a larger memory footprint.

      Workload Profiles

      0.147Score
      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.
