      CPU and System Topology

      Server Description

      A balanced x86_64 virtual server offering dedicated Intel Xeon processing and stable multi-core performance for standard enterprise applications.

      General Purpose

      Alibaba Cloud ecs.g6.4xlarge is a general-purpose virtual machine instance featuring 16 dedicated vCPUs and 64.0 GB of RAM. Powered by an Intel Xeon 8269CY processor running at 2.5 GHz, this x86_64 instance utilizes the KVM hypervisor and provides a balanced 4.0 GB of memory per core. It contains no local storage or GPU accelerators, relying on a baseline network bandwidth of 5 Gbps. Benchmark data indicates average multi-core CPU and memory performance, though single-core performance is relatively weak. The instance is suited for general-purpose workloads, including static web serving, software compilation, and standard database operations.

      Workload Profiles

      0.77Score
      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.
