      CPU and System Topology

      Server Description

      An x86 virtual server offering a high memory-to-core ratio for memory-bound workloads with moderate computational requirements.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.u0.c1m8.xlarge is a memory-optimized virtual server featuring 4 dedicated Intel Xeon 8163 physical cores running at 2.5 GHz and 32.0 GB of RAM. Operating on the x86_64 architecture via the KVM hypervisor, this instance provides a high memory-to-vCPU ratio of 8.0 GB per core but lacks local storage and GPU accelerators. Baseline network bandwidth is rated at 2 Gbps. Performance benchmarks place this instance in the lower tiers, with modest CPU and memory bandwidth results, such as a Geekbench multi-core score of 1993.0 and large-block memory read speeds of 19.83 GB/sec. Qualitatively, it offers a cost-effective option for memory-heavy workloads with low compute demands. It is best suited for lightweight database caching, Redis operations, and memory-bound background tasks.

      Workload Profiles

      0.179Score
      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.
