      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring a high memory-to-vCPU ratio for caching, database operations, and memory-intensive enterprise workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r6.3xlarge is a memory-optimized instance featuring 12 dedicated vCPUs and 96.0 GB of RAM, establishing an 8.0 GB per core memory-to-CPU ratio. Powered by an Intel Xeon 8269CY processor running at 2.5 GHz on the x86_64 architecture, this KVM-based server includes 35 MB of L3 cache and supports AVX-512 instructions. The instance does not feature local storage or GPUs, relying on a baseline network bandwidth of 4 Gbps. Benchmark results show average multi-core CPU and memory bandwidth performance, though single-core performance is weak. With average database operation and Redis SET throughput, this instance is designed for memory-intensive workloads such as caching layers, database hosting, and memory-bound enterprise applications.

      Workload Profiles

      0.628Score
      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.
