1.资源测试
CPU压测
stress --cpu 1 --timeout 600
IO压测
stress -i 1 --timeout 600
进程压测
# centos可能无法模拟，用stress-ng命令
stress -c 8 --timeout 600
stress-ng -i 1 --hdd 1 --timeout 600
上下文压测
sysbench --threads=10 --max-time=300 threads run
读写测试 FIO
https://github.com/iovisor/bcc
# 随机读
fio -name=randread -direct=1 -iodepth=64 -rw=randread -ioengine=libaio -bs=4k -size=1G -numjobs=1 -runtime=1000 -group_reporting -filename=/dev/sdb
# 随机写
fio -name=randwrite -direct=1 -iodepth=64 -rw=randwrite -ioengine=libaio -bs=4k -size=1G -numjobs=1 -runtime=1000 -group_reporting -filename=/dev/sdb
# 顺序读
fio -name=read -direct=1 -iodepth=64 -rw=read -ioengine=libaio -bs=4k -size=1G -numjobs=1 -runtime=1000 -group_reporting -filename=/dev/sdb
# 顺序写

2.网络测试
转发性能
# 开启内核模块
modprobe pktgen
# 执行shell脚本
# 定义一个工具函数，方便后面配置各种测试选项
function pgset() {
local result
echo $1 > $PGDEV
result=`cat $PGDEV | fgrep "Result: OK:"`
if [ "$result" = "" ]; then
cat $PGDEV | fgrep Result:
fi
}
# 为0号线程绑定eth0网卡
PGDEV=/proc/net/pktgen/kpktgend_0
pgset "rem_device_all" # 清空网卡绑定
pgset "add_device eth0" # 添加eth0网卡
# 配置eth0网卡的测试选项
PGDEV=/proc/net/pktgen/eth0
pgset "count 1000000" # 总发包数量
pgset "delay 5000" # 不同包之间的发送延迟(单位纳秒)
pgset "clone_skb 0" # SKB包复制
pgset "pkt_size 64" # 网络包大小
pgset "dst 192.168.0.30" # 目的IP
pgset "dst_mac 11:11:11:11:11:11" # 目的MAC
# 启动测试
PGDEV=/proc/net/pktgen/pgctrl
pgset "start"
#查看结果
$ cat /proc/net/pktgen/eth0
