      CPU and System Topology

      Server Description

      A budget-friendly shared-CPU instance offering balanced multi-core performance for lightweight web serving and caching workloads.

      Compute OptimizedBurstable & Budget

      Alibaba Cloud ecs.n4.2xlarge is an x86_64 virtual server featuring 8 vCPUs and 16.0 GB of RAM, powered by an Intel Xeon 8269CY processor at 2.5 GHz. Operating on a shared CPU allocation model under KVM virtualization, it lacks local storage and dedicated GPUs, relying on a 1 Gbps baseline network bandwidth. Performance benchmarks reveal a contrast between weak single-core capabilities and average multi-core execution, with solid results in software compilation, image processing, and static web serving. Conversely, database operations and single-threaded compression tasks show weaker performance. This instance represents a budget-conscious option for multi-threaded workloads, lightweight Redis caching, and basic web serving, but is not recommended for intensive database hosting or single-threaded computational tasks.

      Workload Profiles

      0.47Score
      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.
