      CPU and System Topology

      Server Description

      An x86_64 memory-optimized server featuring a 1:8 vCPU-to-RAM ratio, designed for database operations and caching workloads without local storage requirements.

      Memory OptimizedGeneral Purpose

      Alibaba Cloud ecs.e4.4xlarge is an x86_64 server featuring 16 vCPUs and 16 physical cores powered by an Intel Xeon E5-2682 v4 processor at 2.5 GHz. Operating on the KVM hypervisor with a shared CPU allocation, it provides 128.0 GB of system memory but lacks local storage and GPU accelerators. Network performance is limited to a 2 Gbps baseline. Benchmarks reveal poor single-core CPU performance, though multi-core metrics, memory bandwidth, and database operations align with average mid-tier standards. This resource profile makes the instance qualitatively cost-effective for memory-heavy, non-compute-intensive workloads. It is best suited for Redis caching, database operations, and static web serving, while being poorly suited for complex LLM inference or tasks requiring high single-threaded performance.

      Workload Profiles

      0.759Score
      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.
