      CPU and System Topology

      Server Description

      A balanced general-purpose instance featuring dedicated Intel Xeon processors, optimized for multi-threaded workloads and standard memory requirements.

      General Purpose

      Alibaba Cloud ecs.g5.3xlarge is a general-purpose virtual machine featuring 12 dedicated vCPUs and 48.0 GB of RAM, powered by an Intel Xeon 8163 processor at 2.5 GHz. Operating on the x86_64 architecture under the KVM hypervisor, this instance lacks local storage and GPU accelerators, relying on a 4 Gbps baseline network bandwidth. Benchmark data reveals a performance trade-off: single-core capabilities are weak, placing in the bottom 25%, while multi-core performance, memory bandwidth, and static web serving throughput consistently reach average mid-tier levels. This hardware profile is best suited for balanced, multi-threaded workloads such as software compilation, static web serving, and Redis database operations where multi-core scaling can offset the lower single-core execution speeds.

      Workload Profiles

      0.47Score
      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.
