web页面与javawebsocket接口的压力测试

web页面与javawebsocket接口的

压力测试

对于网站开发，压力测试是少不了的。压力测试可以对网络，服务器,

系统架构的优化程度进行检验。以便提前知道网站的负载能力，并未

优化提供依据飞

对于网站的压力测试，基本离不开下面两点的测试：W㊀b页面访问的

压力测试和java接口的压力测试（我们接口是通过websocket实

现）。

web页面访问压力测试工具可以使用apache自带的ab命令进行检

测；javawebsocket接口的压力测试可以使用

Jmeter+websocket插件进行检测。

ab安装与使用

一、下载软件

下载地址：

二、进入软件路径

把下载的文件解压到后，用cmd指令进入〃文件夹路径

/Apache24/bin,z

三、获取ab指令参数列表
