      CPU and System Topology

      Server Description

      A dedicated twelve-core compute-optimized instance delivering balanced multi-threaded performance and average memory bandwidth for moderate enterprise workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfc5.3xlarge is an x86_64 compute-optimized server instance featuring 12 dedicated Intel Xeon 6149 CPU cores running at 3.1 GHz and 24.0 GB of RAM. Lacking local storage and GPU accelerators, it relies on network-attached storage and provides a baseline network bandwidth of 2 Gbps. Performance benchmarks reveal a contrast between weak single-core execution and average multi-core capabilities, with stress-ng multi-core, Geekbench multi-core, and Passmark CPU scores all landing in the middle tier. Memory bandwidth is average, though overall memory performance scores are in the bottom quartile. This instance is best suited for multi-threaded workloads, software compilation, Redis operations, and moderate database tasks that benefit from dedicated CPU allocation without requiring high memory-to-vCPU ratios.

      Workload Profiles

      0.501Score
      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.
