      CPU and System Topology

      Server Description

      A dedicated twelve-core compute instance with a balanced memory profile for standard web serving and utility workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.u1-c1m2.3xlarge is an x86_64 compute-focused server featuring 12 dedicated Intel Xeon physical cores running at 2.5 GHz and 24.0 GB of RAM. Operating on the KVM hypervisor, it lacks local storage and integrated GPUs, relying on network-attached storage and a baseline network bandwidth of 4 Gbps. Benchmark results position the instance in the middle tier for general compute, with a PassMark CPU score of 15004.59 and a Geekbench multi-core score of 6824.0. However, it exhibits performance limitations in large-block uncached memory reads and medium LLM inference tasks. This server is best suited for workloads requiring dedicated CPU resources with moderate memory requirements, such as web serving, software compilation, and database operations.

      Workload Profiles

      0.657Score
      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.
