      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring a high memory-to-core ratio for memory-intensive workloads with moderate compute requirements.

      Memory Optimized

      Alibaba Cloud ecs.u1-c1m8.xlarge is an x86_64 memory-optimized server configured with 4 dedicated Intel Xeon physical cores operating at 2.5 GHz and 32.0 GB of RAM. Running on the KVM hypervisor, this instance lacks local storage and GPU accelerators, utilizing a baseline network bandwidth of 2 Gbps. Benchmark data shows average single-core performance in text processing and compression, contrasted by weak multi-core scaling and low memory bandwidth. This hardware profile offers a cost-effective memory allocation of 8.0 GB per core for workloads that prioritize memory capacity over raw compute power. It is best suited for caching systems, lightweight databases, and text processing applications.

      Workload Profiles

      0.278Score
      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.
