      Server Description

      A memory-optimized instance featuring 61 GB of RAM and dedicated Intel Xeon processors for memory-bound legacy workloads.

      Memory OptimizedGeneral Purpose

      Amazon Web Services r4.2xlarge is a memory-optimized, fourth-generation instance designed for workloads requiring a high memory footprint relative to compute resources. Powered by an Intel Xeon E5-2686 v4 processor on the x86_64 architecture, it provides 8 dedicated vCPUs across 4 physical cores, 61.0 GB of RAM, and a 2 Gbps baseline network bandwidth, with no local storage or GPUs. Benchmark data shows modest CPU performance, with single-core and multi-core results falling into the bottom 10% and 25% respectively. However, its uncached large-block memory read bandwidth achieves average performance. This resource profile offers qualitative cost efficiency for memory-heavy legacy applications that do not demand high compute performance. The r4.2xlarge is suited for memory-bound workloads such as caching layers, in-memory databases, and general data processing.

      Workload Profiles

      0.292Score
      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.
