      CPU and System Topology

      Server Description

      A dedicated compute-optimized instance featuring sixteen vCPUs and thirty-two gigabytes of memory for multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.sn1.3xlarge is an x86_64 compute-optimized server utilizing an Intel Xeon 8269CY processor clocked at 2.5 GHz. It provides 16 dedicated vCPUs across 8 physical cores, paired with 32.0 GB of RAM, yielding a 2.0 GB per core memory ratio. The instance lacks local storage and GPU accelerators, relying on a 3 Gbps baseline network bandwidth. Performance benchmarks reveal a divergence between single-core and multi-core capabilities; single-threaded operations are weak, whereas multi-core benchmarks, memory bandwidth, and Redis operations perform at average levels. This hardware profile is qualitatively cost-efficient for multi-threaded workloads that maximize vCPU utilization. It is best suited for static web serving, multi-threaded decompression, and parallelized application tasks.

      Workload Profiles

      0.57Score
      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.
