CPU and System Topology

Server Description

A memory-dense, shared-CPU instance offering balanced multi-core performance and high RAM capacity for database and multi-threaded workloads.

Memory OptimizedGeneral Purpose

Alibaba Cloud ecs.e4.4xlarge is an x86_64 server instance utilizing an Intel Xeon E5-2682 v4 processor at 2.5 GHz. It provides 16 vCPUs across 8 physical cores with a shared CPU allocation, paired with 128.0 GB of RAM and a 2 Gbps baseline network bandwidth. The instance does not include local storage or GPU accelerators. Benchmarks show a significant performance disparity: single-core CPU performance and single-threaded compression tasks rank in the bottom 10% to 25%, whereas multi-core CPU performance, memory bandwidth, and database operations achieve average ratings in the middle 50%. Qualitatively, the server offers high memory density relative to its processing power. It is best suited for memory-intensive, multi-threaded workloads such as database operations, static web serving, and small-scale model inference, rather than compute-heavy or single-threaded applications.

Workload Profiles

0.76Score

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.
