网卡直通性能和桥接性能对比
一 实验环境
硬件环境：
主板：NF5270M3
网卡：I350 *2 firmware-version: 1.61
CPU： E5-2670 v2
软件环境：
Proxmox VE 7.2 with kernel 5.15.30-2-pve
VM:
Ubuntu 18.04.6 LTS with kernel 4.15.0-180-generic igb version: 5.4.0-k
二 实验方案
将网卡分别直通到2个虚拟机，由一根六类线串联。并且使用iperf3进行打流测试。
三 开始实验
直通测试
测试tcp
iperf3 -c 10.2.2.2 -t 20
结果如下
