      CPU and System Topology

      Server Description

      A memory-optimized virtual server with shared vCPUs and 32 GB RAM, designed for lightweight caching and memory-intensive background workloads.

      Memory OptimizedBurstable & BudgetGeneral Purpose

      Alibaba Cloud ecs.e4.xlarge is an x86_64 virtual server featuring 4 shared vCPUs on an Intel Xeon E5-2682 v4 processor running at 2.5 GHz, paired with 32.0 GB of RAM. Operating on the KVM hypervisor, this instance does not include local storage or GPU accelerators, and provides a 1 Gbps baseline network bandwidth. Performance benchmarks place the instance in the lower tiers, with stress-ng single-core performance in the bottom 10% and multi-core performance in the bottom 25%. Large block memory read bandwidth is measured at 30.12 GB/sec. Given its high memory-to-vCPU ratio of 8.0 GB per core alongside shared CPU allocation, the ecs.e4.xlarge is qualitatively cost-efficient for memory-heavy, compute-light workloads. It is best suited for caching layers, lightweight database operations, static web serving, and general-purpose tasks that benefit from a larger memory footprint without requiring high-performance computing.

      Workload Profiles

      0.324Score
      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.
