      CPU and System Topology

      Server Description

      A dedicated memory-optimized virtual server featuring high memory density and Intel Xeon processing for caching and database workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfr7.2xlarge is a memory-optimized instance featuring 8 dedicated vCPUs and 64.0 GB of RAM, delivering an 8:1 memory-to-vCPU ratio. Powered by an Intel Xeon 8369HB processor running at 3.3 GHz, it supports AVX-512 instructions and operates on the KVM hypervisor. The instance lacks local storage and GPUs, relying on a 3 Gbps baseline network bandwidth. Performance benchmarks indicate average capabilities, with a Geekbench multi-core score of 5074.0 and Redis SET operations reaching 7.99 million operations per second. However, it shows limitations in complex tasks, such as weak performance in 7B LLM text generation. This instance is qualitatively cost-efficient for memory-intensive workloads that do not require high-speed local storage, making it suitable for database hosting, caching layers, and in-memory data processing.

      Workload Profiles

      0.55Score
      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.
