      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring a high RAM-to-vCPU ratio for memory-bound workloads requiring dedicated Intel Xeon processor cores.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r6.xlarge is a memory-optimized virtual server instance running on the KVM hypervisor. It is equipped with 4 dedicated vCPUs powered by an Intel Xeon 8269CY processor at 2.5 GHz, alongside 32.0 GB of RAM, which provides a high memory-to-core ratio of 8.0 GB per vCPU. The instance features no local storage and no GPU accelerators, relying on a baseline network bandwidth of 2 Gbps. Benchmark results show average performance in Geekbench single-core and Passmark memory tests, though overall compute and multi-core benchmarks generally fall into the lower 25th percentile. This hardware profile makes the ecs.r6.xlarge qualitatively cost-efficient for memory-heavy, compute-light workloads. It is best suited for in-memory caching, database hosting, and lightweight enterprise applications requiring a larger memory capacity without demanding high CPU throughput.

      Workload Profiles

      0.267Score
      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.
