      CPU and System Topology

      Server Description

      A dedicated 32-core compute-optimized instance designed for parallelized workloads, multi-threaded processing, and high-throughput web serving.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c5.8xlarge is a compute-optimized instance featuring 32 dedicated x86_64 vCPUs powered by an Intel Xeon 8163 processor running at 2.5 GHz. It is configured with 64.0 GB of system memory, yielding a 1:2 vCPU-to-RAM ratio, and provides a 10 Gbps baseline network bandwidth without local storage or GPU accelerators. Benchmark data reveals weak single-core performance but average multi-core capabilities, with multi-threaded stress-ng, Passmark CPU, and Geekbench scores placing in the middle 50 percent. This resource profile offers qualitative cost efficiency for parallelized, compute-bound tasks that do not require high memory density or local disk I/O. It is best suited for workloads such as software compilation, static web serving, and multi-threaded batch processing.

      Workload Profiles

      0.964Score
      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.
