      CPU and System Topology

      Server Description

      A dedicated multi-core compute instance featuring Intel Xeon processors, optimized for parallel workloads and predictable CPU performance without local storage overhead.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c5.4xlarge is an x86_64 compute-optimized server featuring 16 dedicated Intel Xeon 8163 vCPUs running at 2.5 GHz and 32.0 GB of RAM. Lacking local storage and GPU accelerators, it relies on network-attached storage and provides a baseline network bandwidth of 5 Gbps. Performance benchmarks show average multi-core capabilities across stress-ng, Geekbench, and Passmark tests, contrasted by weaker single-core performance. The instance supports AVX-512 and AES instructions, which assists in cryptographic and vector calculations. Qualitatively, the dedicated CPU allocation offers predictable resource density for compute-bound tasks without the premium of bundled storage. It is suitable for multi-threaded workloads, static web serving, Redis deployments, and moderate software compilation.

      Workload Profiles

      0.654Score
      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.
