      CPU and System Topology

      Server Description

      An Arm64-powered virtual machine offering balanced compute and strong memory bandwidth for general-purpose workloads and web serving.

      General Purpose

      Alibaba Cloud ecs.g8y.4xlarge is an Arm64-based general-purpose instance featuring 16 dedicated physical cores on the 2.75 GHz Alibaba Yitian 710 processor. It is configured with 64.0 GB of system memory, 10 Gbps baseline network bandwidth, and no local storage or GPU accelerators. Operating under the KVM hypervisor, the instance delivers balanced performance, highlighted by a strong PassMark memory score in the top 25%. However, benchmarks reveal a relative weakness in cryptographic operations, with the PassMark encryption test falling into the bottom 25%. The instance demonstrates average performance in database operations, static web serving, and small-model LLM inference. It is suited for general-purpose applications, web serving, and multi-threaded decompression tasks, though it is less efficient for heavy cryptographic workloads or larger language model processing.

      Workload Profiles

      1.2Score
      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.
