      Server Description

      A memory-optimized x86_64 virtual server featuring a high memory-to-vCPU ratio and balanced multi-core performance for memory-bound workloads.

      Memory OptimizedStorage & Database

      Amazon Web Services r5n.2xlarge is a memory-optimized instance featuring 8 dedicated vCPUs and 64.0 GB of DDR4 RAM, running on an Intel Xeon 8259CL processor at 3.1 GHz. Built on the Nitro hypervisor, this x86_64 server provides a high memory-to-core ratio of 8.0 GB per core but lacks local storage and GPU accelerators. Performance benchmarks place the instance in the average tier for multi-core CPU execution, memory bandwidth, and database operations, though single-core performance and compression tasks fall into the bottom 25% tier. Network throughput is supported by an 8 Gbps baseline bandwidth. This configuration is suited for memory-intensive workloads, caching layers, and database operations where memory capacity is prioritized over raw single-core compute speed.

      Workload Profiles

      0.444Score
      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.
