OVS-DPDK Performance Benchmark and Analysis with Multi-VMs

Speakers: Lei A Yao and Chenmin Sun, Intel

OVS-DPDK is designed for high performance and widely deployed in cloud service provider today. In the past, there are a lot of performance analysis reports for OVS-DPDK with single VM scenario or limited port numbers. But the typical characteristics of cloud is huge VM numbers and overlay network. In this case, the performance testing will be more complex, and the performance result will be different.

In this talk, we will cover following parts:

Benchmark settings, following part will be considered in test settings: flow numbers, VM numbers, the packet receiving sequence pattern and VXLAN operations.
Performance analysis based on perf and vTune
Hardware limitation to reach rather high throughput
