1. ab

yum install httpd

ab -c 20000 -n 60000 [http://10.1.1.1/][http_10.1.1.1]

2. iperf3

使用iperf测试转发速率可参考如下链接

[https://discuss.aerospike.com/t/benchmarking-throughput-and-packet-count-with-iperf3/2791][https_discuss.aerospike.com_t_benchmarking-throughput-and-packet-count-with-iperf3_2791]

server端运行 iperf3 -s

client端运行 iperf3 -c 1.1.1.1 -p 4567 -i 1 -t 100 -l 88 -V -M 88 -b 1000000000

-l option is the buffer size. Actually this doesn't matter too much.   
    -M option is the MTU size.   The default is 1500.  Here we set it low to get a high packet count. The throughput is set high.
    -p  port number
    -c server IP address
    -t is time for the test in seconds 
    -i option is the interval for output. 
    -b is the bandwidth in bits per second.  This number should be set to the maximum bandwidth for the network interface.

Linux系统下可以运行如下脚本查看网卡实时的封包转发速率

#!/bin/bash
    
    INTERVAL="1"  # update interval in seconds
    
    if [ -z "$1" ]; then
            echo
            echo usage: $0 [network-interface]
            echo
            echo e.g. $0 eth0
            echo
            echo shows packets-per-second
            exit
    fi
    
    IF=$1
    
    while true
    do
            R1=`cat /sys/class/net/$1/statistics/rx_packets`
            T1=`cat /sys/class/net/$1/statistics/tx_packets`
            sleep $INTERVAL
            R2=`cat /sys/class/net/$1/statistics/rx_packets`
            T2=`cat /sys/class/net/$1/statistics/tx_packets`
            TXPPS=`expr $T2 - $T1`
            RXPPS=`expr $R2 - $R1`
            echo "TX $1: $TXPPS pkts/s RX $1: $RXPPS pkts/s"
     done
