      CPU and System Topology

      Server Description

      A memory-optimized cloud server providing an 8:1 RAM-to-vCPU ratio with dedicated Intel Xeon processing and 4 Gbps baseline networking.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r6.3xlarge is a memory-optimized cloud instance built on the x86_64 architecture and powered by a 2.5 GHz Intel Xeon 8269CY processor. It features 12 vCPUs derived from 6 physical cores with hyper-threading, paired with 96.0 GB of RAM to supply an 8.0 GB per vCPU ratio. Built without local disk storage or specialized GPU hardware, the instance relies on network-attached storage and offers a 4 Gbps baseline network bandwidth. Benchmark evaluations highlight solid multi-threaded performance, including a PassMark CPU score of 11,961.29 and Redis throughput of 10.13 million operations per second, alongside average memory read bandwidths up to 584.87 GB/sec. While single-threaded compute performance is moderate, the high memory density provides resource efficiency for memory-bound applications. The instance is suited for in-memory databases, caching tiers, software compilation tasks, and enterprise application servers requiring large RAM capacities.

      Workload Profiles

      0.64Score
      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.
