      CPU and System Topology

      Server Description

      An x86_64 virtual server featuring a high memory-to-core ratio, suitable for memory-bound workloads and caching applications.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.e4.2xlarge is a memory-optimized virtual server featuring 8 vCPUs and 64.0 GB of RAM, running on an Intel Xeon E5-2682 v4 processor at 2.5 GHz. Built on the x86_64 architecture with a KVM hypervisor, this instance utilizes a shared CPU allocation with 1.0 thread per physical core. It includes no local storage or GPU resources, and provides a baseline network bandwidth of 1 Gbps. Performance benchmarks indicate a tradeoff: single-core processing is poor, scoring in the bottom 10% on stress-ng, whereas multi-core and memory bandwidth metrics reach average tiers. The high memory-to-vCPU ratio of 8.0 GB per core offers qualitative cost efficiency for memory-intensive applications. It is best suited for workloads such as Redis caching, static web serving, and memory-heavy database operations that do not demand sustained single-core compute power.

      Workload Profiles

      0.541Score
      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.
