      CPU and System Topology

      Server Description

      A dedicated general-purpose virtual instance offering a balanced resource profile and steady multi-core performance for standard enterprise workloads.

      General Purpose

      Alibaba Cloud ecs.n2.3xlarge is a general-purpose instance featuring 16 vCPUs and 64.0 GB of RAM, running on an Intel Xeon 8163 processor with x86_64 architecture. Utilizing the KVM hypervisor, it provides a dedicated CPU allocation across 8 physical cores with hyper-threading. The instance does not include local storage or GPU accelerators. Benchmark data reveals a contrast between weak single-core performance and average multi-core execution, with mid-range results in multi-threaded Geekbench, Passmark, and Redis SET operations. Memory bandwidth also performs in the average tier. Given its balanced 1:4 vCPU-to-RAM ratio and dedicated CPU resources, the ecs.n2.3xlarge is qualitatively cost-effective for workloads that do not require high-frequency single-thread processing. It is best suited for multi-threaded applications, general-purpose web serving, database operations, and software compilation.

      Workload Profiles

      0.73Score
      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.
