      Server Description

      A memory-optimized server featuring 32 GB of RAM and dedicated Intel Xeon processors for memory-bound workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r6i.xlarge is a memory-optimized instance featuring 4 dedicated vCPUs from a 3.5 GHz Intel Xeon 8375C processor and 32.0 GB of DDR4 RAM. Operating on the AWS Nitro hypervisor, this x86_64 server lacks local storage and GPUs, relying on a 2 Gbps baseline network connection. Benchmark data shows average single-core performance, with a Geekbench single-core score of 1595.0, but weaker multi-core and memory bandwidth results, such as a multi-core Geekbench score of 3423.0 and 29.13 GB/sec large-block read bandwidth. While multi-threaded decompression and database operations are relatively weak, the instance maintains average performance in static web serving and single-threaded compression. The r6i.xlarge is qualitatively cost-effective for memory-intensive, low-compute workloads, making it a suitable fit for caching layers, text processing, and small-scale database deployments.

      Workload Profiles

      0.357Score
      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.
