      CPU and System Topology

      Server Description

      A dedicated multi-core x86_64 compute resource with a 1:2 memory-to-vCPU ratio, optimized for parallelized workloads with moderate memory needs.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.n1.7xlarge is an x86_64 server featuring 32 dedicated vCPUs from an Intel Xeon 8163 processor running at 2.5 GHz, paired with 64.0 GB of memory. It does not include local storage or a GPU. While single-core benchmarks fall into the lower percentiles, its multi-core capabilities reach average performance tiers, as shown by a stress-ng multi-core score of 29309.22. The 1:2 vCPU-to-RAM ratio makes it a resource-dense option for parallel workloads with moderate memory requirements. It is suitable for multi-threaded tasks, software compilation, and static web serving, though it presents tradeoffs in single-threaded speed and memory capacity.

      Performance

      Workload Profiles

      1.1Score
      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.
