      CPU and System Topology

      Server Description

      A compute-optimized x86_64 server with dedicated Intel Xeon processors, balanced memory, and 10 Gbps network bandwidth for compute-intensive workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c7nex.2xlarge is a compute-optimized x86_64 server instance featuring 8 dedicated vCPUs and 16.0 GB of RAM, powered by an Intel Xeon 8369B processor at 2.7 GHz. Operating on a KVM hypervisor, it provides a baseline network bandwidth of 10 Gbps but lacks local storage and GPU accelerators. Performance benchmarks place this instance in the average tier, with a stress-ng multi-core score of 7750.38 and a static web serving throughput of 11.46 GB/sec. Its 1:2 vCPU-to-RAM ratio makes it a qualitatively cost-efficient choice for compute-intensive workloads that do not demand high memory density. It is well-suited for web serving, software compilation, and database operations.

      Workload Profiles

      0.58Score
      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.
