      CPU and System Topology

      Server Description

      A dedicated compute-optimized instance with sixteen vCPUs and average multi-threaded performance for parallelized workloads without local storage requirements.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c6.4xlarge is an x86_64 compute-optimized server instance featuring 16 dedicated vCPUs and 32.0 GB of RAM, powered by an Intel Xeon 8269CY processor at 2.5 GHz. Operating on the KVM hypervisor, it lacks local storage and GPU accelerators, utilizing a 5 Gbps baseline network bandwidth. Performance benchmarks show a distinct contrast: single-core performance is weak, falling into the bottom 25% for single-threaded compression and stress-ng tests. However, multi-core performance and memory bandwidth consistently rank in the average tier, with a multi-core Geekbench score of 7299.0 and a Passmark CPU score of 15380.43. This resource profile makes the instance suitable for multi-threaded applications, software compilation, database operations, and static web serving, provided workloads do not require high single-thread performance or local SSD storage.

      Workload Profiles

      0.77Score
      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.
