      CPU and System Topology

      Server Description

      A dedicated compute-optimized virtual server featuring 16 vCPUs and AVX-512 support for processing-heavy workloads without local storage overhead.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c4.4xlarge is a compute-optimized virtual server built on the KVM hypervisor and powered by a dedicated 3.2 GHz Intel Xeon 8369HB processor. Utilizing the x86_64 architecture, it features 16 vCPUs (8 physical cores) and 32.0 GB of system memory, providing a 2.0 GB per core ratio. The instance does not include local storage or GPU accelerators, but delivers a baseline network bandwidth of 6 Gbps. Benchmark results indicate average performance across standard compute tasks, with a Geekbench multi-core score of 7455.0 and a static web serving throughput of 9.51 GB/sec. While memory performance is relatively weak, the dedicated CPU allocation and AVX-512 support make it highly suitable for compute-intensive workloads such as software compilation, web serving, and moderate database operations.

      Workload Profiles

      0.85Score
      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.
