      CPU and System Topology

      Server Description

      A dedicated eight-core x86_64 compute instance with low memory density, optimized for lightweight processing and static web serving.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.u1-c1m1.2xlarge is an x86_64 compute-focused instance featuring 8 dedicated Intel Xeon physical cores (8 vCPUs) running at 2.5 GHz, paired with 8.0 GB of RAM. Operating on a KVM hypervisor, this server does not include local storage or GPU hardware, and provides a baseline network bandwidth of 2 Gbps. Benchmark results show average performance, with a Passmark CPU score of 10428.01 and a Geekbench multi-core score of 5272.0. Memory bandwidth reaches 59.61 GB/sec for uncached large blocks, while static web serving throughput averages 9.4 GB/sec. Due to its low memory-to-CPU ratio of 1.0 GB per core, this instance is best suited for compute-bound workloads with small memory footprints, such as software compilation, static web serving, and lightweight text or image processing.

      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.
