      CPU and System Topology

      Server Description

      A dedicated dual-core compute instance with a 1:2 memory-to-CPU ratio, designed for lightweight stateless workloads and basic web serving.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c6.large is an entry-level, compute-optimized instance featuring 2 dedicated vCPUs and 4.0 GB of RAM. Powered by an Intel Xeon 8269CY processor running at 2.5 GHz on the x86_64 architecture, this KVM-based server provides a 1:2 vCPU-to-RAM ratio. It contains no local storage or GPUs, relying on a 1 Gbps baseline network connection. Benchmark results show modest performance, with a stress-ng single-core score of 1303.98 and a multi-core score of 1735.19. Memory bandwidth is limited, reaching 12.93 GB/sec for uncached large-block reads. This instance is best suited for lightweight workloads such as basic web serving, small Redis deployments, and stateless microservices.

      Workload Profiles

      0.147Score
      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.
