Comparative Performance Analysis of I/O Interfaces on Different NVMe SSDs in a High CPU Contention Scenario

Abstract

This paper analyzes performance differences between interrupt-based and polling-based asynchronous I/O interfaces in high CPU contention scenarios. It examines how the choice of I/O Interface can differ depending on the performance of NVMe SSDs, particularly when using PCIe 3.0 and PCIe 4.0-based SSDs.
