      CPU and System Topology

      Server Description

      An entry-level, memory-optimized virtual server featuring a high memory-to-CPU ratio for lightweight caching and basic database workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.u0.c1m8.large is an entry-level, memory-optimized x86_64 server instance powered by 2 dedicated vCPUs from an Intel Xeon 8163 processor running at 2.5 GHz. It features 16.0 GB of RAM, providing a high 8.0 GB of memory per core, but lacks local storage and GPU acceleration. Baseline network bandwidth is rated at 1 Gbps. Benchmark results place this instance in the lower performance tiers, with stress-ng and Geekbench scores falling in the bottom 10% to 25% range. Large-block memory write bandwidth is limited to 9.35 GB/sec. Given its high memory-to-CPU ratio and modest processing capabilities, this instance is qualitatively cost-effective for memory-heavy, compute-light workloads. It is best suited for lightweight caching layers, small Redis deployments, static web serving, and basic database operations.

      Workload Profiles

      0.105Score
      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.
