      CPU and System Topology

      Server Description

      A memory-optimized x86_64 instance featuring 128 GB RAM and 16 vCPUs, designed for multi-threaded workloads and database operations.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.e3.3xlarge is an x86_64 memory-optimized server instance featuring 16 vCPUs and 128.0 GB of RAM, powered by an Intel Xeon 8163 processor running at 2.5 GHz. Built on a KVM hypervisor, it allocates 8 physical cores with hyper-threading and lacks local storage and GPU accelerators. Performance benchmarks reveal a distinct tradeoff: single-core and single-threaded operations, such as gzip compression, perform poorly, ranking in the bottom 10% to 25%. Conversely, multi-core workloads, memory bandwidth, and database operations achieve average tier performance. This resource profile makes the ecs.e3.3xlarge qualitatively cost-efficient for memory-intensive, multi-threaded workloads like database operations, static web serving, and software compilation, where massive single-core speed is not the primary bottleneck.

      Workload Profiles

      0.8Score
      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.
