      CPU and System Topology

      Server Description

      A memory-optimized virtual server featuring 256 GB RAM and 32 dedicated cores, balanced for multi-threaded and database workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.se1.8xlarge is a memory-optimized virtual server featuring 32 dedicated physical cores on an Intel Xeon 8269CY processor running at 2.5 GHz. It is equipped with 256.0 GB of RAM, offering a high 8.0 GB of memory per core, but lacks local storage and GPU accelerators. The instance operates on the KVM hypervisor and provides a baseline network bandwidth of 6 Gbps. Performance benchmarks reveal a distinct tradeoff: single-core capabilities are weak, placing in the bottom 25%, while multi-core and memory bandwidth metrics consistently reach average levels. This resource profile makes the ecs.se1.8xlarge qualitatively cost-effective for memory-heavy, multi-threaded workloads. It is best suited for database operations, caching systems, and general-purpose memory-intensive applications that do not demand high single-threaded CPU performance.

      Workload Profiles

      0.941Score
      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.
