      CPU and System Topology

      Server Description

      A shared-CPU instance with thirty-two virtual cores and sixty-four gigabytes of memory for parallelized, network-dependent workloads.

      Compute OptimizedBurstable & Budget

      Alibaba Cloud ecs.n4.8xlarge is an x86_64 compute-optimized server featuring 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, this KVM-based instance provides 2.0 GB of memory per core and lacks local storage, relying instead on network-attached storage with a 5 Gbps baseline bandwidth. Performance benchmarks reveal weak single-core capabilities, placing in the bottom 10%, but average multi-core performance across stress-ng, Geekbench, and multi-threaded decompression tests. This resource profile makes the instance qualitatively cost-effective for parallelized, multi-threaded workloads that can tolerate shared CPU resources. It is best suited for tasks such as static web serving, software compilation, and database operations.

      Workload Profiles

      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.
