      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring dedicated AMD EPYC cores and a high RAM-to-vCPU ratio for low-concurrency, memory-bound workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r7a.large is an x86_64 memory-optimized virtual server featuring 2 dedicated vCPUs and 16.0 GB of RAM, powered by an AMD EPYC 7T83 processor at 2.55 GHz. It operates on the KVM hypervisor with a 1 Gbps baseline network bandwidth, but lacks local storage and GPU accelerators. Performance benchmarks show a strong single-core stress-ng CPU score in the top 25%, contrasted by weak multi-core and memory bandwidth metrics, with both uncached write bandwidth and Redis SET operations ranking in the bottom 10%. The instance is qualitatively cost-efficient for memory-heavy, low-concurrency workloads. It is best suited for lightweight caching, single-threaded data processing, and small-scale memory-intensive applications.

      Workload Profiles

      0.147Score
      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.
