      CPU and System Topology

      Server Description

      A dedicated four-core processor instance with a compact memory footprint, optimized for lightweight single-threaded and CPU-bound utility workloads.

      Compute OptimizedBurstable & Budget

      Alibaba Cloud ecs.u1-c1m1.xlarge is an x86_64 virtual server powered by the KVM hypervisor and equipped with 4 dedicated Intel Xeon physical cores running at 2.5 GHz. It features 4.0 GB of RAM, providing a 1:1 vCPU-to-RAM ratio, with no local storage or GPU hardware. While single-core benchmarks for tasks like compression and text processing perform in the average tier, multi-core and memory bandwidth benchmarks are weak. This resource configuration represents a clear tradeoff, offering dedicated processing cores alongside highly constrained memory capacity. Consequently, this instance is best suited for lightweight, CPU-bound workloads that do not demand significant memory, such as basic single-threaded utility tasks, text processing, or small-scale development environments.

      Workload Profiles

      0.284Score
      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.
