      CPU and System Topology

      Server Description

      A high-density compute instance featuring dedicated Intel Xeon processors, optimized for multi-threaded decompression and database operations without local storage overhead.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfc6.16xlarge is a compute-optimized instance featuring 64 dedicated vCPUs and 128.0 GB of RAM, powered by an Intel Xeon 8269CY processor running at 3.1 GHz. Built on the KVM hypervisor, this x86_64 server lacks local storage and GPUs, instead offering a 20 Gbps baseline network bandwidth. Performance benchmarks indicate strong capabilities in multi-threaded bzip3 decompression, large-block read-only memory bandwidth, and PassMark database operations, all placing in the top 25 percent. Standard compute tasks, including stress-ng and Redis SET operations, perform in the average range, while LLM text generation is a relative bottleneck. This instance provides a cost-efficient profile for CPU-intensive workloads like database operations, web serving, and data decompression that do not require local SSDs or hardware acceleration.

      Workload Profiles

      2.4Score
      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.
