      Server Description

      An ARM64 memory-optimized instance featuring a high memory-to-core ratio and dedicated vCPUs for lightweight, memory-bound workloads.

      Memory Optimized

      Amazon Web Services r8gn.large is a memory-optimized instance featuring 2 dedicated vCPUs and 2 physical cores powered by an AWS Graviton ARMv9 Neoverse-V2 processor. Operating on the ARM64 architecture at 2.8 GHz, it provides 16.0 GB of system memory, resulting in a high 8.0 GB per core allocation, alongside a 6 Gbps baseline network bandwidth. The instance lacks local storage and GPU accelerators. Performance benchmarks show average single-core CPU capabilities and strong single-threaded bzip3 decompression, though multi-core performance, memory write speeds, and cryptographic execution are weak or poor. Qualitatively, the r8gn.large offers a cost-efficient entry point for memory-bound workloads that do not demand heavy parallel processing. It is suited for lightweight database operations, caching, and memory-intensive web serving.

      Workload Profiles

      0.31Score
      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.
