      CPU and System Topology

      Server Description

      A dedicated 32-core Arm-based compute instance delivering strong multi-threaded decompression and database performance with a balanced memory profile.

      Compute Optimized

      Alibaba Cloud ecs.c8y.8xlarge is an arm64 compute-optimized server powered by the 2.75 GHz Alibaba Yitian 710 processor. It features 32 dedicated physical cores with a 1:1 thread-to-core ratio, 64.0 GB of RAM, and a 16 Gbps baseline network bandwidth, with no local storage or GPU hardware. In benchmark testing, the instance demonstrates strong performance in multi-threaded bzip3 decompression and database operations, both ranking in the top 25%. Other metrics, such as stress-ng CPU performance and Redis SET operations, align with average tiers. The custom Arm architecture provides high physical core density, though it lacks x86-specific vector extensions like AVX. This instance is suited for multi-threaded decompression, database operations, static web serving, and moderate-scale machine learning inference.

      Workload Profiles

      1.93Score
      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.
