calico性能测试

硬件环境：

三台虚拟机：

192.168.99.129 master（kube-apiserver、kube-controller-manager、kube-proxy、kube-scheduler、kubelet、etcd、calico、docker）

192.168.99.130 slave1（kube-proxy、kubelet、etcd proxy、calico、docker、dns）

192.168.99.131 slave2（kube-proxy、kubelet、etcd proxy、calico、docker）

软件环境：

kubernetes 1.5.2

etcd 3.1.0

calico 0.23.1

qperf （网络性能测试工具，安装方法：yum install -y qperf）

测试结果：
