      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring a high RAM-to-vCPU ratio and stable multi-core performance for database and caching workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.r6.2xlarge is an x86_64 memory-optimized instance featuring 8 dedicated vCPUs and 64.0 GB of RAM, powered by an Intel Xeon 8269CY processor at 2.5 GHz. Operating on the KVM hypervisor, this instance provides a high memory-to-core ratio of 8.0 GB per core but lacks local storage and GPU accelerators. Performance benchmarks show average multi-core CPU capabilities, with a Passmark CPU score of 8268.09 and Redis SET performance at 6.84 million operations per second, though single-core performance is relatively weak. Memory bandwidth is stable, reaching 49.43 GB/sec for uncached large-block reads. Given its high memory density and moderate compute performance, the ecs.r6.2xlarge is qualitatively cost-efficient for memory-bound applications. It is highly suitable for database operations, caching layers, and in-memory data processing.

      Workload Profiles

      0.452Score
      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.
