      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring a high memory-to-core ratio for lightweight database hosting and memory-cached applications.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.u1-c1m8.large is a memory-optimized virtual machine instance built on the KVM hypervisor. It is equipped with an x86_64 Intel Xeon processor running at 2.5 GHz, delivering 2 dedicated physical cores and 2 vCPUs. The instance features 16.0 GB of system memory, providing a high ratio of 8.0 GB of RAM per core, but lacks local storage and GPU accelerators. Network connectivity is established at a baseline of 1 Gbps. Benchmark data reveals average single-core performance alongside weaker multi-core and memory bandwidth results. This resource profile offers qualitative cost efficiency for memory-heavy, low-compute workloads. It is best suited for lightweight database operations, caching layers, and general-purpose applications that benefit from a larger memory footprint without requiring high multi-threaded processing power.

      Workload Profiles

      0.18Score
      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.
