      CPU and System Topology

      Server Description

      An Arm64 compute-optimized virtual server featuring dedicated physical cores for efficient web serving and high-throughput key-value store workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c8y.2xlarge is an Arm64 compute-optimized instance featuring 8 dedicated physical cores of an Alibaba Yitian710 processor running at 2.75 GHz, paired with 16.0 GB of RAM. Running on the KVM hypervisor, this server lacks local storage and GPU accelerators but provides a baseline network bandwidth of 5 Gbps. Benchmark data indicates average performance across standard compute and memory tasks, with a stress-ng multi-core score of 14489.92 and a cached read memory bandwidth of 820.26 GB/sec. While cryptographic performance is weak, the instance excels in high-throughput scenarios, delivering 13.18 million Redis SET operations per second and 12.71 GB/sec in static web serving. It represents a resource-dense, cost-efficient option for scale-out workloads, web serving, and lightweight Arm-native applications.

      Workload Profiles

      0.72Score
      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.
