      CPU and System Topology

      Server Description

      A memory-optimized instance featuring 128 GB of RAM and 16 dedicated cores, balancing average multi-core throughput with high memory density.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.e3.3xlarge is an x86_64 memory-optimized instance featuring 16 dedicated physical cores on an Intel Xeon 8163 processor running at 2.5 GHz. It is equipped with 128.0 GB of RAM, providing a 1:8 vCPU-to-memory ratio, and operates without local storage or GPU accelerators. Benchmark results indicate a performance tradeoff: single-core CPU execution and single-threaded compression tasks are weak to poor, whereas multi-core performance, database operations, and static web serving throughput achieve average ratings. Memory bandwidth remains average for both cached and uncached operations, though the overall memory benchmark score is weak. This instance is qualitatively cost-efficient for memory-heavy applications that leverage multi-threaded execution, making it suitable for caching layers, database operations, and static web serving.

      Workload Profiles

      0.799Score
      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.
