      CPU and System Topology

      Server Description

      A dedicated compute-optimized instance featuring sixteen vCPUs and thirty-two gigabytes of memory for balanced multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c6e.4xlarge is a compute-optimized instance featuring 16 dedicated vCPUs and 32.0 GB of system memory, powered by an Intel Xeon 8269CY processor running at 2.5 GHz. Built on the KVM hypervisor, this x86_64 architecture instance provides a 1:2 vCPU-to-RAM ratio, 6 Gbps of baseline network bandwidth, and contains no local storage or GPU accelerators. Benchmark data reveals average multi-core performance alongside weaker single-core execution, with stable memory read bandwidth of 86.1 GB/sec for large blocks. The dedicated CPU allocation ensures consistent performance for multi-threaded workloads. This instance is best suited for compute-intensive tasks such as software compilation, web serving, and database operations that do not demand high local storage capacities or massive memory allocations.

      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.
