      CPU and System Topology

      Server Description

      A shared-CPU x86_64 instance offering thirty-two vCPUs and sixty-four gigabytes of memory for parallelized, multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.n4.8xlarge is an x86_64 server instance equipped with 32 vCPUs and 64.0 GB of RAM, powered by an Intel Xeon 8163 processor at 2.5 GHz. Operating on a shared CPU allocation model under the KVM hypervisor, this instance lacks local storage and GPU acceleration, relying on a 5 Gbps baseline network bandwidth. Benchmark data reveals a significant contrast in performance: single-core metrics for CPU and compression tasks fall into the bottom 10%, whereas multi-core benchmarks, including Geekbench and Passmark CPU tests, reach average tiers. Memory bandwidth remains average, though overall memory performance scores are weak. This hardware profile makes the instance suitable for parallelized workloads, static web serving, and Redis operations that benefit from multi-threaded execution but do not require high single-core speed or dedicated CPU resources.

      Workload Profiles

      0.991Score
      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.
