      CPU and System Topology

      Server Description

      A compute-optimized virtual server featuring dedicated high-frequency processors and a balanced memory-to-CPU ratio for compute-intensive workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfc6.6xlarge is a compute-optimized virtual server featuring 24 dedicated vCPUs and 48.0 GB of RAM, powered by an Intel Xeon 8269CY processor running at 3.1 GHz on the x86_64 architecture. Operating under the KVM hypervisor, this instance provides a 2.0 GB per vCPU memory ratio and lacks local storage or GPU hardware, utilizing an 8 Gbps baseline network bandwidth. Benchmark results indicate solid mid-range performance, with a stress-ng multi-core score of 23003.67, a Redis SET throughput of 21.93 million operations per second, and a static web serving throughput of 16.94 GB/sec. The instance is optimized for compute-heavy, memory-lean workloads such as software compilation, web serving, and text processing, offering a balanced resource profile for applications that require dedicated CPU cycles without massive memory or local storage demands.

      Workload Profiles

      1.2Score
      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.
