      CPU and System Topology

      Server Description

      A balanced general-purpose virtual server offering dedicated multi-core processing and steady memory bandwidth for standard enterprise workloads.

      General Purpose

      Alibaba Cloud ecs.g6.3xlarge is a general-purpose instance featuring 12 dedicated vCPUs and 48.0 GB of RAM, powered by an Intel Xeon 8269CY processor running at 2.5 GHz. Built on the x86_64 architecture with the KVM hypervisor, this instance provides a balanced 1:4 vCPU-to-RAM ratio but does not include local storage or GPU accelerators. Benchmark data reveals a performance tradeoff: single-core metrics, such as stress-ng single-core and single-threaded gzip compression, rank in the bottom 25%, whereas multi-core performance, memory bandwidth, and database operations consistently achieve average, middle-50% tier results. With a baseline network bandwidth of 4 Gbps, the ecs.g6.3xlarge is designed for multi-threaded workloads that do not demand high single-core speeds, making it suitable for static web serving, software compilation, and Redis database operations.

      Performance

      Workload Profiles

      0.63Score
      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.
