      CPU and System Topology

      Server Description

      An arm64 compute-optimized instance featuring 32 dedicated physical cores for parallelized workloads, software compilation, and multi-threaded web serving.

      Compute Optimized

      Alibaba Cloud ecs.c6r.8xlarge is an arm64 compute-optimized instance featuring a 2.8 GHz Ampere Altra processor with 32 dedicated physical cores, 32 vCPUs, and 64.0 GB of RAM. Running on the KVM hypervisor, it lacks local storage and GPU accelerators, utilizing an 8 Gbps baseline network bandwidth. Benchmark data indicates average multi-core performance, highlighted by a strong multi-threaded bzip3 decompression speed of 217.66 GB/sec, alongside average memory bandwidth and database operations. Conversely, single-core performance is relatively weak, as shown in Geekbench and single-threaded compression tests. This instance is qualitatively cost-efficient for parallelized, non-storage-intensive workloads. It is best suited for multi-threaded web serving, software compilation, containerized microservices, and arm64 development environments.

      Workload Profiles

      1.67Score
      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.
