物理机性能评测
ping延迟
登录到10.100.100.244,运行ping 10.100.100.245
测试延迟:
root@hc0:~# ping 10.100.100.245

平均值为: 0.244842ms
注:可以通过下面的脚本例子计算ping延迟的平均值
root@hc0:~# ping 10.100.100.245 | head -n 20 | gawk '/time/ {split($7, ss, "="); sum+=ss[2]; count+=1;} END{print sum/count "ms";}'
0.244842ms
相互之间多次ping测试。延迟一般在0.22ms-0.26ms之间
iperf带宽
apt-get install iperf 安装iperf后,在10.100.100.245上启动iperf server:
iperf -s
,在10.100.100.244上启动客户端,执行下面命令:root@hc0:~# iperf -c 10.100.100.245 -i 1

nginx benchmark
先在10.100.100.244上,执行
docker run --net=host nginx
启动一个单进程的nginx服务,然后在10.100.100.245上使用ab -n 90000 -c 50 http://10.100.100.244/
开始压测,结果如下:root@hc1:~# ab -n 90000 -c 50 http://10.100.100.244/

ping延迟
在pod之间的ping延迟,启动两个iperf pod,启动在不同的host上。然后执行下面的命令获得ping延迟:
root@hc0:~/yaml# kubectl get pod -owide --all-namespaces
NAMESPACE NAME READY STATUS RESTARTS AGE IP NODE
net1-sub1 net-test-4v9av 1/1 Running 0 29s 192.168.11.33 10.100.100.245
