      Server Description

      A memory-optimized, network-enhanced virtual server featuring dedicated Intel Xeon processors and high-density DDR4 RAM for database and caching workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6in.2xlarge is a memory-optimized, network-optimized instance built on the AWS Nitro hypervisor. It features an Intel Xeon 8375C processor running at 3.5 GHz, delivering 8 vCPUs across 4 physical cores with hyperthreading. The instance is equipped with 64.0 GB of DDR4 memory, providing a high memory-to-vCPU ratio of 8 GB per vCPU, but lacks local storage and dedicated GPUs. It provides a baseline network bandwidth of 12 Gbps. Benchmarks indicate solid average performance across standard compute, memory bandwidth, and database operations, such as Redis SET operations at 7.98 million operations per second. However, it exhibits weaker performance in multi-threaded decompression and larger LLM inference tasks. This instance is best suited for memory-intensive workloads, caching layers, and database deployments that rely on network-attached storage.

      Workload Profiles

      0.62Score
      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.
