      CPU and System Topology

      Server Description

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

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r5.6xlarge is a memory-optimized instance featuring 24 dedicated vCPUs and 192.0 GB of RAM, yielding an 8.0 GB per-core memory ratio. Powered by an Intel Xeon 8163 processor at 2.5 GHz on the x86_64 architecture, it operates on a KVM hypervisor and provides a baseline network bandwidth of 8 Gbps. This instance does not include local storage or GPU accelerators. Performance benchmarks indicate average multi-core CPU and memory bandwidth capabilities, contrasted by weaker single-core and single-threaded compression performance. Qualitatively, it represents a balanced option for memory-intensive applications that prioritize high RAM capacity over peak single-thread speed. It is best suited for database operations, Redis caching, and static web serving.

      Workload Profiles

      0.784Score
      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.
