      Server Description

      A memory-optimized virtual instance featuring 122 GB of RAM and 16 dedicated vCPUs for memory-intensive database and web serving workloads.

      Memory Optimized

      Amazon Web Services r4.4xlarge is a memory-optimized instance featuring 16 dedicated vCPUs and 122.0 GB of RAM, powered by an Intel Xeon E5-2686 v4 processor running at 2.3 GHz. Built on the x86_64 architecture and managed via the Xen hypervisor, this instance does not include local storage or GPU resources, but provides a baseline network bandwidth of 5 Gbps. Benchmark data shows poor single-core performance, but average multi-core and memory read bandwidth capabilities. This resource profile makes the instance highly suitable for memory-intensive workloads such as database operations, static web serving, and software compilation, where massive memory capacity is required but single-threaded CPU speed is not the primary bottleneck. It offers a cost-effective option for memory-bound legacy applications.

      Workload Profiles

      0.491Score
      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.
