      CPU and System Topology

      Server Description

      A balanced x86_64 virtual instance offering dedicated Intel Xeon compute resources and steady memory bandwidth for standard enterprise workloads.

      General Purpose

      Alibaba Cloud ecs.u1-c1m4.4xlarge is a general-purpose instance featuring 16 dedicated vCPUs and 64.0 GB of RAM, running on an Intel Xeon x86_64 processor at 2.5 GHz. Utilizing the KVM hypervisor, this instance provides a balanced 1:4 vCPU-to-RAM ratio with 4.0 GB of memory per core, a 33 MB L3 cache, and a baseline network bandwidth of 5 Gbps. It does not include local storage or GPU hardware. Benchmark results indicate steady, average-tier performance, with a Geekbench multi-core score of 8674.0 and a Redis SET throughput of 15.3 million operations per second. The instance is qualitatively cost-effective for standard workloads that do not require high-speed local NVMe or specialized accelerators. It is best suited for general-purpose applications such as static web serving, database operations, software compilation, and moderate data processing.

      Workload Profiles

      0.89Score
      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.
