      CPU and System Topology

      Server Description

      A dedicated twelve-core compute instance with a balanced memory-to-core ratio for multi-threaded processing and web serving workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c6.3xlarge is an x86_64 compute-optimized server instance featuring 12 dedicated physical cores on an Intel Xeon 8269CY processor clocked at 2.5 GHz. Configured with 24.0 GB of RAM, it maintains a 2.0 GB per core ratio and operates on the KVM hypervisor. The instance does not include local storage or GPUs, and it delivers a baseline network bandwidth of 4 Gbps. Performance benchmarks show a contrast between weak single-core execution and average multi-core capabilities, with stress-ng multi-core, PassMark CPU, and Redis SET operations all scoring in the middle 50% tier. This hardware profile is suited for multi-threaded workloads, static web serving, and database operations that benefit from dedicated CPU resources without requiring high memory density.

      Workload Profiles

      0.615Score
      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.
