      CPU and System Topology

      Server Description

      A dedicated Intel-powered instance featuring 128 GB of memory and 16 vCPUs optimized for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfr7.4xlarge is a memory-optimized instance running on the KVM hypervisor, featuring a dedicated Intel Xeon 8369HB processor. It provides 16 vCPUs clocked at 3.3 GHz, paired with 128.0 GB of RAM, yielding a high memory-to-vCPU ratio of 8.0 GB per core. The instance lacks local storage and GPU accelerators, but features a baseline network bandwidth of 6 Gbps. Benchmark results demonstrate solid performance, with a stress-ng multi-core score of 16666.15 and a Redis SET throughput of 16.05 million operations per second. This hardware profile is highly suited for memory-intensive workloads, such as in-memory databases, caching layers, and enterprise applications that require dedicated compute resources and high memory density without the need for local NVMe storage.

      Workload Profiles

      0.95Score
      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.
