      CPU and System Topology

      Server Description

      A memory-optimized instance with a high RAM-to-vCPU ratio, delivering balanced multi-core performance for caching and database workloads.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.se1.4xlarge is a memory-optimized instance featuring 16 dedicated vCPUs and 128.0 GB of RAM, powered by an Intel Xeon 8269CY processor at 2.5 GHz on the x86_64 architecture. It lacks local storage and GPU accelerators, relying on a baseline network bandwidth of 3 Gbps. Benchmark data reveals a significant performance tradeoff: single-core performance is weak to poor, whereas multi-core execution and memory bandwidth consistently achieve average ratings. This resource profile makes the instance highly cost-effective for memory-bound workloads that benefit from a high RAM-to-vCPU ratio without requiring top-tier single-threaded processing power. It is best suited for database operations, Redis caching, static web serving, and multi-threaded data processing.

      Workload Profiles

      0.564Score
      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.
