      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring dedicated Intel processors and a high RAM-to-vCPU ratio for memory-intensive, compute-light workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.u0.c1m8.2xlarge is an x86_64 memory-optimized server instance featuring 8 dedicated Intel Xeon 8163 vCPUs running at 2.5 GHz and 64.0 GB of RAM. Operating on a KVM hypervisor, this instance provides a high memory-to-vCPU ratio of 8.0 GB per core, though it lacks local storage and GPU accelerators. Benchmark data indicates modest compute and memory read performance, with stress-ng and Geekbench scores generally falling into the lower percentiles, while large-block memory write speeds and small-model LLM inference align with average tiers. With a baseline network bandwidth of 2 Gbps, this instance is qualitatively cost-efficient for memory-heavy, compute-light applications. It is best suited for workloads such as caching systems, small database operations, and lightweight enterprise applications requiring a larger memory footprint without intensive processing demands.

      Workload Profiles

      0.316Score
      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.
