      CPU and System Topology

      Server Description

      A budget-friendly, shared-core virtual server offering sixteen vCPUs for multi-threaded workloads requiring moderate compute and memory capacity.

      Burstable & BudgetCompute Optimized

      Alibaba Cloud ecs.n4.4xlarge is an x86_64 virtual server featuring 16 vCPUs and 32.0 GB of RAM, powered by an Intel Xeon 8163 processor at 2.5 GHz. Operating under a KVM hypervisor with a shared CPU allocation, this instance does not include local storage or GPU accelerators, and provides a baseline network bandwidth of 2 Gbps. Benchmark data reveals weak single-core CPU and memory performance, but average multi-core scaling, as seen in stress-ng multi-core and Geekbench multi-core tests. This resource profile offers a budget-friendly option for multi-threaded workloads that do not require dedicated CPU cores. It is well-suited for static web serving, software compilation, and multi-threaded decompression, while remaining less optimal for single-threaded processing or memory-intensive database operations.

      Workload Profiles

      0.746Score
      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.
