      CPU and System Topology

      Server Description

      An entry-level, compute-focused instance featuring dedicated Intel Xeon cores and a balanced 1:2 memory-to-CPU ratio for basic workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c5.xlarge is an x86_64 compute-optimized instance featuring 4 dedicated physical cores powered by an Intel Xeon 8163 processor running at 2.5 GHz. It is configured with 8.0 GB of RAM, yielding a 1:2 vCPU-to-RAM ratio, and contains no local storage or GPU accelerators. Network connectivity is limited to a baseline bandwidth of 2 Gbps. In benchmark testing, the instance consistently performs in the lower tiers, with stress-ng CPU and Passmark memory scores falling into the bottom 10% to 25% of results. Large-block memory read bandwidth is particularly constrained at 20.58 GB/sec. Given these performance characteristics and the dedicated CPU allocation, this instance is best suited for entry-level compute tasks, basic web serving, and lightweight database operations that do not demand high memory bandwidth or local storage.

      Workload Profiles

      0.219Score
      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.
