      CPU and System Topology

      Server Description

      A multi-core general-purpose server offering balanced memory and dedicated compute resources for parallelized workloads and web serving.

      General Purpose

      Alibaba Cloud ecs.sn2.13xlarge is a general-purpose instance configured with 56 dedicated vCPUs and 224.0 GB of RAM, running on an Intel Xeon 8269CY processor at 2.5 GHz. It features an x86_64 architecture with 28 physical cores, a 35 MB L3 cache, and a 10 Gbps baseline network bandwidth, with no local storage or GPU hardware. Performance benchmarks show a contrast between weak single-core capabilities in the bottom 25% and average multi-core and memory bandwidth performance in the middle 50% tier. This resource distribution makes the instance qualitatively cost-effective for highly parallelized tasks rather than single-threaded operations. It is best suited for multi-threaded workloads, static web serving, Redis deployments, and moderate database operations.

      Workload Profiles

      1.3Score
      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.
