      CPU and System Topology

      Server Description

      An x86_64 compute instance with 16 dedicated vCPUs, balanced multi-core performance, and a 1:2 memory-to-CPU ratio.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.n1.3xlarge is an x86_64 server instance featuring 16 vCPUs and 32.0 GB of RAM, powered by an Intel Xeon 8163 processor running at 2.5 GHz. It operates on the KVM hypervisor with dedicated CPU allocation, though it lacks local storage and GPU acceleration. Benchmarks reveal weak single-core performance, with stress-ng and Geekbench single-core scores in the bottom 25%, and poor text processing capabilities. However, its multi-core performance, memory bandwidth, and database operations fall within average ranges. With a 1:2 vCPU-to-RAM ratio, this instance is suited for parallelized workloads such as static web serving, software compilation, and Redis caching, where multi-threaded scaling can offset the lower single-core efficiency.

      Workload Profiles

      0.8Score
      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.
