      CPU and System Topology

      Server Description

      A dedicated general-purpose virtual server with balanced memory and compute resources for entry-level utility workloads.

      General Purpose

      Alibaba Cloud ecs.u1-c1m4.xlarge is a general-purpose virtual machine featuring 4 dedicated x86_64 vCPUs and 16.0 GB of RAM, running on an Intel Xeon processor at 2.5 GHz. Utilizing the KVM hypervisor, this instance provides a balanced 1:4 vCPU-to-RAM ratio but lacks local storage and GPU acceleration. Baseline network performance is rated at 2 Gbps. Benchmark results place this instance in the lower performance tier, with a Geekbench multi-core score of 2281.0 and a Passmark CPU score of 4175.8. It is qualitatively structured as a cost-effective option for workloads requiring dedicated but modest compute resources. The instance is best suited for lightweight web serving, basic database operations, and utility application hosting.

      Workload Profiles

      0.25Score
      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.
