Intel® Data Streaming Accelerator (DSA) – Offloading Memory Copying in VPP by Shared Memory Packet Interface (memif) Plugin with Intel® DSA on 4th Gen Intel® Xeon® Scalable Processors

Last Updated: Oct 27, 2023

This document outlines the deployment of VPP memif with Direct Memory Access (DMA) option to accelerate memory copying. Through comparing the benchmarking results for various packet sizes with MTU 1500 and MTU 9000 between Software Mode (without Intel® DSA) and Hardware Mode (with Intel® DSA) , there is up to 1.9x throughput improvement with 0.001% packet loss rate on 4th Gen Intel ® Xeon® Scalable Processor with Intel® E810 Network Controllers.
