      CPU and System Topology

      Server Description

      A dedicated multi-core compute instance with a 1:2 memory-to-CPU ratio, optimized for parallelized workloads and static web serving.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.sn1.3xlarge is a compute-optimized instance featuring 16 dedicated Intel Xeon 8269CY vCPUs and 32.0 GB of RAM. Operating on the x86_64 architecture with a 2.5 GHz clock speed, this KVM-based server provides a 1:2 RAM-to-vCPU ratio. It does not include local storage or GPU hardware, relying on a 3 Gbps baseline network bandwidth. Benchmark data reveals a clear tradeoff, with weak single-core CPU and memory performance but average multi-core scaling, as seen in software compilation and multi-threaded decompression tests. This profile makes the instance suitable for parallelized workloads, static web serving, and moderate database operations where multi-threaded efficiency is prioritized over single-threaded speed.

      Workload Profiles

      0.571Score
      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.
