      CPU and System Topology

      Server Description

      A compute-optimized x86_64 platform featuring dedicated Intel Xeon processors and high-speed network bandwidth for processing-heavy workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c7nex.4xlarge is an x86_64 compute-optimized server instance featuring 16 dedicated vCPUs from an Intel Xeon 8369B processor running at 2.7 GHz, paired with 32.0 GB of RAM. Lacking local storage and GPU accelerators, the instance relies on network-attached storage and provides a baseline network bandwidth of 20 Gbps. Benchmark evaluations indicate balanced performance, with a stress-ng multi-core score of 15531.0, a static web serving throughput of 20.56 GB/sec, and a Redis SET capability of 15.7 million operations per second. The 1:2 vCPU-to-RAM ratio makes this instance efficient for CPU-intensive workloads such as web serving, software compilation, and database operations that do not demand high memory capacity or local storage.

      Workload Profiles

      1Score
      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.
