      Server Description

      A memory-optimized server featuring high-capacity DDR4 RAM and enhanced network bandwidth for database and memory-intensive workloads.

      Memory OptimizedStorage & Database

      Amazon Web Services r5n.8xlarge is a memory-optimized and network-optimized instance featuring 32 vCPUs and 16 physical cores powered by a dedicated 3.1 GHz Intel Xeon 8259CL processor. It is equipped with 256.0 GB of DDR4 memory, providing 8.0 GB of RAM per core, and operates on the Nitro hypervisor. The instance lacks local storage, relying on EBS optimization, and features a baseline network bandwidth of 25 Gbps. Performance benchmarks show weak single-core capabilities but average multi-core performance, memory bandwidth, and Redis database operations. This resource profile makes the instance suitable for memory-intensive workloads, database deployments, and network-bound applications.

      Workload Profiles

      1.2Score
      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.
