      CPU and System Topology

      Server Description

      A memory-optimized x86_64 server featuring 192 GB of RAM and dedicated Intel Xeon processors for memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.hfr6.6xlarge is an x86_64 memory-optimized server featuring a dedicated Intel Xeon 8269CY processor with 24 vCPUs (12 physical cores) running at 3.1 GHz. It is equipped with 192.0 GB of RAM, yielding a high 8.0 GB per vCPU ratio, but lacks local storage and GPU accelerators. Network connectivity is established at an 8 Gbps baseline. In benchmark testing, the instance demonstrates average-tier performance, achieving a multi-core stress-ng score of 22989.57 and 22.01 million operations per second in Redis SET tests. Large block uncached memory read bandwidth is measured at 107.74 GB/sec. Lacking local NVMe drives, this server relies entirely on network storage. It is structurally configured for memory-intensive applications, including in-memory databases, caching layers, and data processing workloads that leverage its 35 MB L3 cache and AVX-512 vector extensions.

      Workload Profiles

      1.2Score
      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.
