      Server Description

      A memory-optimized virtual server featuring a high RAM-to-vCPU ratio for database operations and multi-threaded memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r5.4xlarge is a memory-optimized instance featuring 16 dedicated vCPUs from an Intel Xeon 8259CL processor running at 3.1 GHz, paired with 128.0 GB of DDR4 memory. Built on the Nitro hypervisor, this x86_64 instance lacks local storage and GPUs, relying on a 5 Gbps baseline network connection. Benchmark data positions its single-core performance in the bottom 25% tier, while multi-core CPU, memory bandwidth, and database operations consistently achieve average performance within the middle 50% tier. With a high 8:1 memory-to-vCPU ratio, the r5.4xlarge is qualitatively cost-efficient for memory-heavy workloads. It is highly suited for database operations, caching layers, and multi-threaded processing.

      Workload Profiles

      0.77Score
      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.
