[quote=引用 8 楼 jiao_zg 的回复:] [quote=引用 2 楼 huhui_bj 的回复:] 至于相应时间，可以用IE9自带的工具，按F12就能启动，左上角有个“网络”，然后点击旁边的开始捕获，它会返回一个网站的响应时间。 不明白再给我留言
我用的是ie8，按了f12，但是没找到“网络”。。。[/quote] 我说的是IE9，你可以升级到IE9，然后试试。下面是查看csdn首页的响应时间效果图： [/quote] 谢谢，现在直接慢的不用浏览器测，直接就感觉到了，得好几秒钟

怎么使用？菜鸟求指教[/quote] 你不是要测试你的网站压力吗？你只要把final URL url = new URL("http://www.ucas.ac.cn");语句中替换成你自己的url，有域名就写域名，没有域名就直接写"http://localhost:8080/项目页面",用线程模拟人的访问。然后调整concurrentNum的大小，即线程模拟数目。[/quote]非常感谢！刚刚测了一下，首页打开，开了20个线程，超级超级慢

至于相应时间，可以用IE9自带的工具，按F12就能启动，左上角有个“网络”，然后点击旁边的开始捕获，它会返回一个网站的响应时间。
不明白再给我留言

我用的是ie8，按了f12，但是没找到“网络”。。。[/quote]
我说的是IE9，你可以升级到IE9，然后试试。下面是查看csdn首页的响应时间效果图：

如果只是简单测试连接，1L的方法简单易行； 如果要模拟真实用户操作，LoadRunner是好些，不过它安装占用很大空间，脚本录制需要学习，而且收费的（当然，也是有破解方法）（再当然下，selenium免费，类似LR）。 建议还是用1L的线程方法，可以把run写复杂点，多做些操作~
