      Server Description

      A memory-optimized virtual instance featuring a high memory-to-vCPU ratio and dedicated Intel Xeon processing for memory-intensive workloads.

      Memory Optimized

      The Amazon Web Services r5n.xlarge is a memory-optimized instance utilizing the Nitro hypervisor and an x86_64 Intel Xeon 8259CL processor running at 3.1 GHz. It features 4 dedicated vCPUs across 2 physical cores and is equipped with 32.0 GB of DDR4 memory, yielding an 8:1 memory-to-vCPU ratio. No local storage or GPU accelerators are included. Network connectivity is established with a baseline bandwidth of 4 Gbps. Performance benchmarks show weak ratings for multi-core CPU tasks and memory bandwidth, though single-core Geekbench and Passmark memory scores reach average levels. This resource profile presents a tradeoff of high memory density against lower compute and memory bandwidth speeds. It is designed for memory-intensive workloads such as caching layers, database operations, and applications requiring a larger memory footprint relative to compute power.

      Workload Profiles

      0.257Score
      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.
