      Server Description

      A memory-optimized instance featuring a high RAM-to-vCPU ratio for caching layers and database workloads with moderate compute requirements.

      Memory Optimized

      Amazon Web Services r5.xlarge is a memory-optimized instance featuring 4 dedicated vCPUs and 32.0 GB of DDR4 RAM. Powered by an Intel Xeon 8259CL processor running at 3.1 GHz on the Nitro hypervisor, it provides an 8:1 memory-to-vCPU ratio. The instance does not include local storage and operates with a baseline network bandwidth of 1 Gbps. Benchmark results indicate weak overall CPU performance, with stress-ng and Passmark CPU scores falling in the bottom 25%, though its Passmark memory score is average. Lacking a GPU and high-speed network interfaces, the r5.xlarge is best suited for memory-intensive workloads with moderate compute demands, such as caching layers, small databases, and basic in-memory data processing.

      Workload Profiles

      0.264Score
      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.
