      CPU and System Topology

      Server Description

      A dedicated sixteen-core compute instance designed for multi-threaded workloads, web serving, and moderate database operations without bundled storage.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfc5.4xlarge is a compute-optimized instance featuring 16 dedicated x86_64 physical cores powered by an Intel Xeon 6149 processor running at 3.1 GHz. It is configured with 32.0 GB of RAM, providing a 2.0 GB per core ratio, and contains no local storage or GPU accelerators. Operating on the KVM hypervisor, the instance delivers a baseline network bandwidth of 3 Gbps. Benchmark data indicates average multi-core performance and memory bandwidth, though single-core execution speeds are positioned in the lower tier. This resource profile offers a balanced, dedicated compute environment without the cost of excess memory. The ecs.hfc5.4xlarge is well-suited for multi-threaded workloads such as static web serving, software compilation, Redis operations, and medium-scale database tasks.

      Workload Profiles

      0.637Score
      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.
