      CPU and System Topology

      Server Description

      A compute-optimized x86_64 server with dedicated Intel Xeon cores and high network throughput for CPU-intensive processing tasks.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c7nex.4xlarge is a compute-optimized instance featuring 16 dedicated physical cores powered by an Intel Xeon 8369B processor running at 2.7 GHz on an x86_64 architecture. It is equipped with 32.0 GB of RAM, providing a 2.0 GB memory-per-core ratio, and offers a baseline network bandwidth of 20 Gbps. The instance does not include local storage or GPU accelerators. In benchmark testing, the server demonstrates solid mid-range performance, achieving a stress-ng multi-core score of 15531.0, a Redis SET throughput of 15.7 million operations per second, and a static web serving throughput of 20.56 GB/sec. The lack of local storage and moderate memory-to-vCPU ratio represent clear tradeoffs, positioning this instance as a cost-efficient option for CPU-intensive workloads, multi-threaded decompression tasks, and high-throughput web serving.

      Workload Profiles

      1.01Score
      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.
