      CPU and System Topology

      Server Description

      A dedicated eight-core compute-optimized instance with a two-to-one vCPU-to-RAM ratio, designed for CPU-bound workloads and static web serving.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c4.2xlarge is an x86_64 compute-optimized instance featuring 8 dedicated Intel Xeon 8369HB physical cores running at 3.2 GHz and 16.0 GB of RAM. Operating on the KVM hypervisor, this instance provides a 1:2 vCPU-to-RAM ratio, 3 Gbps baseline network bandwidth, and no local storage or GPU accelerators. Benchmark results indicate average performance in general compute tasks, software compilation, and static web serving, alongside average single-core and multi-core stress-ng scores. However, memory performance is a notable tradeoff, with uncached large-block read bandwidth and database operations falling into the bottom 25% tier. The CPU supports AVX-512 and VNNI, which assists with lightweight vector calculations, though larger model inference remains poor. This instance is suited for compute-bound workloads with moderate memory requirements, such as web serving, compilation, and basic image processing.

      Workload Profiles

      0.527Score
      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.
