      CPU and System Topology

      Server Description

      A balanced general-purpose x86 server providing 24 vCPUs, 96 GiB memory, and multi-core processing capacity for enterprise application backends.

      General Purpose

      Alibaba Cloud ecs.g5.6xlarge is a general-purpose instance powered by a 2.5 GHz Intel Xeon 8163 processor on x86_64 architecture, providing 12 physical cores, 24 vCPUs, and 96 GiB of system RAM. It incorporates an 8 Gbps baseline network speed, operates under a KVM hypervisor, and contains no local storage or GPUs. Performance testing demonstrates solid multi-threaded capability with a PassMark CPU score of 18227.84 and a multi-core stress-ng score of 17544.06, though single-core performance registers lower across Geekbench and gzip compression tests. Large uncached block memory read throughput reaches 90.15 GB/sec. In application benchmarks, it yields 16.81 million operations per second on Redis SET tasks and 13.07 GB/sec in static web serving. The balanced 1:4 vCPU-to-memory ratio aligns with microservices, web application servers, CI/CD build environments, and in-memory caching platforms.

      Performance

      Workload Profiles

      0.86Score
      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.
