      Server Description

      A memory-optimized instance featuring a high RAM-to-vCPU ratio and average multi-core performance for memory-intensive database and caching workloads.

      Memory Optimized

      Amazon Web Services r5n.4xlarge is an x86_64 memory-optimized instance featuring 16 vCPUs and 128.0 GB of DDR4 memory, running on an Intel Xeon 8259CL processor at 3.1 GHz. Built on the Nitro hypervisor, it provides a dedicated CPU allocation with 8 physical cores and a baseline network bandwidth of 16 Gbps, though it lacks local storage and GPU accelerators. Benchmark data reveals a performance tradeoff: single-core CPU performance and single-threaded compression tasks are weak, falling into the bottom 25%, whereas multi-core CPU performance, memory bandwidth, and database operations consistently rank in the average tier. This hardware profile is qualitatively cost-efficient for memory-heavy applications that do not demand high single-core processing speeds. The r5n.4xlarge is suited for memory-intensive workloads such as database operations, Redis caching, and static web serving.

      Workload Profiles

      0.76Score
      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.
