      CPU and System Topology

      Server Description

      An Arm64 compute-optimized instance featuring sixteen dedicated physical cores and balanced memory bandwidth for efficient web serving and database workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c8y.4xlarge is an Arm64 compute-optimized instance featuring 16 dedicated physical cores powered by the Alibaba Yitian YiTian710 processor running at 2.75 GHz. It is configured with 32.0 GB of RAM, providing a 1:2 vCPU-to-RAM ratio, and offers a baseline network bandwidth of 10 Gbps with no local storage. Performance benchmarks indicate average CPU and memory capabilities, highlighted by a strong PassMark memory score and solid multi-threaded decompression speeds. However, cryptographic performance is relatively weak. This instance is qualitatively cost-efficient for Arm-native workloads, making it suitable for web serving, database operations, and general compute-intensive applications that do not require specialized x86 instructions or local storage.

      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.
