支持多队列的网卡

Single-core CPU performance cannot meet the requirement of processing NIC interruptions incurred with the increase of network I/O bandwidth. NIC multi-queue enables multiple CPUs to process ECS NIC interruptions, thereby improving network PPS and I/O performance.

  1. 查看系统是否支持多队列网卡
 lspci -vvv | grep "MSI-X: Enable+ " 

#输出: 说明做大支持64队列
Capabilities: [70] MSI-X: Enable+ Count=64 Masked-

2.查看网卡是否支持多队列

ethtool -l eth0
#输出：

Channel parameters for eth0:
 Pre-set maximums:
 RX:             0
 TX:             0
 Other:          1
 Combined:       63 #网卡支持64队列
 Current hardware settings:
 RX:             0
 TX:             0
 Other:          1
 Combined:       8  #目前设置为支持8队列

3.开启多队列

#开启两个队列
 [root@localhost ~]# ethtool -L eth0 combined 2
