      CPU and System Topology

      Server Description

      An x86_64 general-purpose virtual server with dedicated Intel Xeon processors and balanced memory for standard enterprise workloads.

      General Purpose

      Alibaba Cloud ecs.u1-c1m4.2xlarge is an x86_64 general-purpose instance featuring an Intel Xeon processor with 8 dedicated vCPUs, 4 physical cores, and a 2.5 GHz clock speed. It is equipped with 32.0 GB of RAM, a 33 MB L3 cache, and a baseline network bandwidth of 2 Gbps, but lacks local storage and GPU accelerators. Benchmark data indicates average performance across standard workloads, with a Geekbench multi-core score of 5300.0 and a static web serving throughput of 9.56 GB/sec. However, it exhibits weak performance on larger computational tasks, such as medium-sized LLM inference. This instance is qualitatively cost-efficient for balanced, non-storage-intensive workloads, making it suitable for general-purpose applications, software compilation, Redis deployments, and moderate web serving.

      Workload Profiles

      0.53Score
      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.
