      CPU and System Topology

      Server Description

      A dedicated 24-core compute-optimized instance with a balanced memory-to-core ratio for multi-threaded processing and web serving workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c6.6xlarge is a compute-optimized instance featuring 24 dedicated physical cores on an Intel Xeon 8269CY x86_64 processor running at 2.5 GHz. It is configured with 48.0 GB of RAM, providing a 2.0 GB per core ratio, and lacks local storage and GPU accelerators. Operating on the KVM hypervisor, the instance delivers a baseline network bandwidth of 8 Gbps. Benchmark data shows average multi-core CPU performance with a stress-ng score of 21007.3 and a PassMark CPU score of 21643.62, though single-core performance is weaker. With an average Redis SET throughput of 20.09 million operations per second and static web serving throughput of 15.86 GB/sec, this instance is suited for multi-threaded compute workloads, web serving, and database operations that do not require local disk storage.

      Workload Profiles

      1.06Score
      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.
