      CPU and System Topology

      Server Description

      A dedicated dual-core AMD EPYC instance with a 1:2 vCPU-to-RAM ratio, optimized for lightweight single-threaded tasks and basic development environments.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c6a.large is an x86_64 compute-optimized instance featuring 2 dedicated vCPUs and 2 physical cores powered by an AMD EPYC 7H12 processor running at 2.6 GHz. It is configured with 4.0 GB of RAM, providing 2.0 GB per core, and features a 1 Gbps baseline network bandwidth. The instance does not include local storage or GPU accelerators. Benchmark data indicates average performance in single-threaded operations, such as gzip compression and Geekbench single-core tests, but poor performance in multi-core execution, memory bandwidth, and database operations. Given these performance trade-offs, the ecs.c6a.large is a cost-effective option for dedicated CPU allocation suited for lightweight single-threaded workloads, basic web serving, and development environments rather than memory-intensive or highly parallelized applications.

      Workload Profiles

      0.136Score
      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.
