      CPU and System Topology

      Server Description

      An ARM64 compute-optimized instance featuring dedicated physical cores and balanced multi-threaded performance for web serving and compilation workloads.

      Compute Optimized

      Alibaba Cloud ecs.c6r.2xlarge is an ARM-based compute-optimized instance featuring 8 dedicated physical cores powered by an Ampere Altra processor at 2.8 GHz. It is equipped with 16.0 GB of RAM, providing a 2.0 GB per-core memory allocation, and operates on a KVM hypervisor with a 2 Gbps baseline network bandwidth. The instance does not include local storage or GPU accelerators. Performance benchmarks show average multi-core capabilities, with a stress-ng multi-core score of 14295.27, but weaker single-core performance, as reflected in its Geekbench single-core score of 1104.0. Memory bandwidth is moderate, reaching 92.39 GB/sec for uncached large blocks. Lacking advanced vector extensions, this instance offers a cost-efficient physical core density for multi-threaded workloads. It is best suited for static web serving, software compilation, and database operations.

      Workload Profiles

      0.591Score
      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.
