      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring a high RAM-to-vCPU ratio and dedicated Intel Xeon processors for memory-intensive workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r6.3xlarge is a memory-optimized instance featuring 12 dedicated Intel Xeon vCPUs and 96.0 GB of RAM on an x86_64 architecture. Running at 2.5 GHz, this KVM-based server lacks local storage and GPUs, but provides a 4 Gbps baseline network bandwidth. Benchmarks show weak single-core performance alongside average multi-core, memory bandwidth, and database execution capabilities. It is suited for in-memory databases and caching workloads.

      Workload Profiles

      0.634Score
      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.
