      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring a high memory-to-vCPU ratio, dedicated Intel Xeon processors, and balanced multi-core performance.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.se1.8xlarge is a memory-optimized instance featuring 32 dedicated vCPUs and 256.0 GB of RAM, powered by an Intel Xeon 8269CY processor at 2.5 GHz. Built on the x86_64 architecture and KVM hypervisor, it provides 8 GB of memory per vCPU but lacks local storage and GPU accelerators. Performance benchmarks reveal a distinct tradeoff: single-core processing and single-threaded compression are weak, placing in the bottom 25%, whereas multi-core execution, memory bandwidth, and database operations achieve average, middle-tier results. With a baseline network bandwidth of 6 Gbps, this instance is qualitatively cost-efficient for memory-intensive applications that rely on parallel processing rather than raw single-threaded speed. It is best suited for database hosting, Redis deployments, and multi-threaded enterprise workloads.

      Workload Profiles

      0.94Score
      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.
