      CPU and System Topology

      Server Description

      A dedicated 64-core compute-optimized platform delivering strong multi-threaded performance and high-speed memory bandwidth for intensive processing workloads.

      Compute Optimized

      Alibaba Cloud ecs.hfc6.16xlarge is a compute-optimized instance featuring 64 dedicated physical cores powered by an Intel Xeon 8269CY processor running at 3.1 GHz. Built on the x86_64 architecture and KVM hypervisor, it provides 128.0 GB of RAM, resulting in a 2.0 GB per core memory allocation. The instance does not include local storage or GPU accelerators but offers a baseline network bandwidth of 20 Gbps. Benchmark data highlights strong multi-core CPU performance, high multi-threaded decompression speeds, and strong database operations. However, LLM text generation performance is weak. This instance is qualitatively cost-efficient for high-compute workloads requiring dedicated CPU resources without local storage needs. It is highly suitable for multi-threaded processing, database operations, and software compilation.

      Workload Profiles

      2.42Score
      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.
