      CPU and System Topology

      Server Description

      A compute-optimized x86_64 server featuring sixteen dedicated Intel Xeon cores and a balanced two-to-one vCPU-to-RAM ratio for compute-heavy workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfc6.4xlarge is an x86_64 compute-optimized server instance featuring 16 dedicated physical cores and 16 vCPUs powered by an Intel Xeon 8269CY processor running at 3.1 GHz. It is equipped with 32.0 GB of RAM, providing 2.0 GB of memory per core, but lacks local storage and GPU accelerators. Network performance is anchored by a 5 Gbps baseline bandwidth. Benchmark data indicates average performance across standard compute and memory tests, with a stress-ng multi-core score of 15316.01 and a Redis SET throughput of 15.25 million operations per second. Due to its 1:2 vCPU-to-RAM ratio and lack of local storage, this instance is designed for compute-heavy workloads such as software compilation, web serving, and database operations that rely on external storage, offering a balanced resource density for non-memory-intensive deployments.

      Workload Profiles

      0.853Score
      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.
