      CPU and System Topology

      Server Description

      A dedicated twelve-core compute instance with a one-to-two processor-to-memory ratio, optimized for parallelized, multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c5.3xlarge is an x86_64 compute-optimized instance featuring 12 dedicated vCPUs on an Intel Xeon 8163 processor running at 2.5 GHz. Equipped with 24.0 GB of RAM, it provides a 1:2 vCPU-to-memory ratio, with no local storage or GPU resources. Operating on the KVM hypervisor, the instance delivers a baseline network bandwidth of 4 Gbps. Performance benchmarks show weak single-core capabilities but average multi-core and memory bandwidth results, making it a balanced choice for parallel processing. The primary tradeoff is its low memory allocation per core and weak single-threaded performance. It is best suited for multi-threaded workloads such as software compilation, static web serving, and moderate multi-threaded decompression tasks.

      Workload Profiles

      0.537Score
      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.
