      CPU and System Topology

      Server Description

      An arm64-powered instance with sixteen dedicated cores and balanced memory for predictable multi-threaded computing and web serving.

      General Purpose

      Alibaba Cloud ecs.g6r.4xlarge is an arm64-based general-purpose instance featuring 16 dedicated physical cores powered by an Ampere Altra processor running at 2.8 GHz. It is configured with 64.0 GB of system memory, providing 4.0 GB of RAM per core, and operates on the KVM hypervisor with a baseline network bandwidth of 5 Gbps. The instance does not include local storage or GPU accelerators. Benchmark data indicates stable multi-threaded performance, with a multi-core stress-ng score of 28603.05 and a Redis SET throughput of 21.74 million operations per second. However, it exhibits lower performance in single-threaded bzip3 decompression and Passmark CPU encryption tests. This instance offers a balanced resource profile, making it suitable for static web serving, Redis caching, and general-purpose multi-threaded workloads.

      Workload Profiles

      0.993Score
      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.
